Accelerating Large Image and Signal Processing FPGA Design Developments with TySOM-3A-ZU19EG and PYNQ   
Developing for larger Heterogeneous SoC like the Xilinx MPSoC UltraScale+ EG19 device present the developer with several challenges, from timing closure to developing the software and demonstrating increasing technology readiness level (TRL) as the product develops. One of the largest challenges if the integration of the programmable logic algorithm with the application software, this needs to not only correctly be able to configure and access design elements implemented in the programmable logic but also implement the higher-level algorithms and application. TySOM embedded development board enables the developer to hit the ground running and start developing the application for both the programmable logic and software solution from day one. By leveraging the PYNQ framework the developers can accelerate the development of algorithms and verification of programmable logic design. PYNQ provides the developer with the ability to control AXI peripherals within the programmable logic using Python and Jupyter notebooks, opening the wider python ecosystem for development and verification of the algorithms. This is especially beneficial for image and signal processing applications. This session will demonstrate how developers can use the TySOM-3A-ZU19EG embedded development board and the PYNQ framework can be combined to accelerate your developments for image and signal processing applications. Play webinar

Accelerating The Verification Of Hardware Dependent Software   
Software costs now dominate in SoC design. It is therefore imperative that the dependencies the hardware places on the software are captured and managed as early as possible. To ignore these is to risk project and budget overrun. In this webinar, we will illustrate why FPGAs are chosen as the verification platform for software integration. We will discuss the challenges of using FPGAs for verification and introduce the use of hybrid virtual prototypes. A comparison will be made between traditional FPGA ASIC prototypes and an FPGA-based emulation system. Play webinar

Accelerating Verification Component development with OSVVM Model Independent Transactions   
Verification components have become an essential part of a structured VHDL environment. In OSVVM we implement verification components as an entity and architecture. This provides RTL engineers with a familiar environment to create model behavior.    The objective of any verification framework is to make the Device Under Test (DUT) "feel like" it has been plugged into the board. Hence, the framework must be able to produce the same waveforms and sequences of waveforms that the DUT will see on the board. The OSVVM testbench framework looks identical to other frameworks, including SystemVerilog. It includes verification components (AxiStreamTransmitter and AxiStreamReceiver) and TestCtrl (the test sequencer) as shown in Figure 1. The top level of the testbench connects the components together (using the same methods as in RTL design) and is often called a test harness. Connections between the verification components and TestCtrl use VHDL records (which we call the transaction interface).   Connections between the verification components and the DUT are the DUT interfaces (such as AxiStream, UART, AXI4, SPI, and I2C).   There are three steps required to create an OSVVM verification component: Define the transaction interface (in OSVVM it is a record) Define the transaction procedures (the call API for the test sequencer) Define the internals of the verification component itself.   OSVVM model independent transactions are one of our latest innovations – added to OSVVM in 2020.07. For a class of interfaces, the model independent transactions define the transaction interface and transaction procedures. OSVVM has defined these for address bus interfaces (such as AXI, Avalon, X86, …) and streaming type interfaces (such as UART, AXI Stream, …).    For a testbench/verification component developer, using the model independent transactions allows a developer to focus on just the internals of the verification component. Directive transactions can be copied from models of a similar class. This helps save time in testbench development. For the test case developer, model independent transactions provide address bus interfaces and streaming interfaces with a common set of transactions (API). This makes writing test cases easier since the transaction interface (API) is already familiar.  This also facilitates either re-use of test sequences between different verification components or porting tests from one interface to another.    This webinar provides a guided walk-through of the OSVVM model independent transactions. Benefits of OSVVM OSVVM is a competitive solution with SystemVerilog + UVM for FPGA Verification.   World-wide, 18% of the FPGA market uses OSVVM [1] – or alternately 36% of the VHDL FPGA market uses OSVVM. In Europe, in the FPGA market, OSVVM (with 36%) leads SystemVerilog+UVM (with 26%).     OSVVM is an innovator and leader in the development of VHDL Verification Methodology. Our approach has been evolving in SynthWorks classes since 1997 and started being released as open source in 2011. So how does it compare to SystemVerilog? Constrained Random – Supported via RandomPkg and coding styles – an OSVVM innovation Functional Coverage – Supported via CoveragePkg – an OSVVM innovation Scoreboards – Supported via ScoreboardGenericPkg – an OSVVM innovation Error reporting and Messaging – supported via AlertLogPkg – concepts borrowed from numerous sources Transaction based testbenches and verification components – in our classes since 1997 Memory Modeling – data structure for efficient creation of memories through sparse allocation. Process Synchronization – barrier synchronization (an OSVVM innovation) as well as other methods. Is OSVVM supported by my simulator? Currently OSVVM is supported by simulators from Mentor, Aldec, Cadence, Synopsys, and GHDL. This is great support and our goal is to keep it this way. When we upgrade existing features in the library, we test to make sure we do not break support within our community. OTOH, when we introduce new capability (generally in separate packages) and there is a significant advantage to using advanced VHDL constructs – such as it simplifies how the item is used, then it is likely we will use it – as a result, some of OSVVM's Verification IP uses records with unconstrained arrays.  We also strictly avoid using deprecated language features - such as shared variables that have an ordinary type. Play webinar

Addressing the Challenges of SoC Verification in practice using Co-Simulation   
Heterogeneous System on Chip (SoC) devices like the Xilinx Zynq 7000 and Zynq UltraScale+ MPSoC combine a high-performance processing systems (PS) with state of the art programmable logic (PL). This combination allows system to be architected to provide an optimal solution. Verifying this interaction between the PS and PL presents a challenge to the design team. While each can be verified in isolation using QEMU for the PS and Riviera-PRO for the PL. The integration between the PS and PL all too often takes place late in the design cycle when the impact of addressing issues raised is larger in both time and cost. There is however, another way which is Co-Simulation, which can be performed early in the development cycle. This webinar will explore the challenges which are faced by SoC users, introduce the concept of Co-Simulation and its constituent parts along with demonstrating advanced debugging techniques. We will examine the required environment and pre-requisites needed to perform Co-Simulation. Detailed examples will then be presented to demonstrate basic and advanced debugging concepts. Based upon a Zynq implementing a Pulse Width Modulation IP core operating under SW control. We will look at examples which introduce basic Co-Simulation flow like waveform inspection along with advanced debugging aspects such as software and Hardware breakpoints and single stepping. These techniques will enable us to identify and debug issues which reside in both the software and hardware design. Co-Simulation enables you to develop your application faster and reduce the bring up time once the application hardware arrives for integration. This webinar will demonstrate these benefits and more which are gained when Co-Simulation is used, while demonstrating the ease with which the environment can be established and simulation performed. Play webinar

Aiding ASIC Design Partitioning for multi-FPGA Prototyping   
Whether it is an ASIC, ASSP or large FPGA design, emulation and prototyping are indispensable verification and validation activities. Often FPGA based platforms are chosen due to their scalability and versatility and more importantly, because of their runtime speed potential. What drives many away from this platform are the challenges of the multi-FPGA design setup that requires complex partitioning, arranging interconnections and managing multiple clock domains across multiple devices. Automation in this field is highly desirable to avoid time consuming and error prone hand-crafting and design hacks that would enable FPGA prototyping. Aldec HES™ Prototyping Platform and related solutions are here to mitigate these risks and facilitate rapid implementation of reliable FPGA prototypes. Design setup for a large multi-FPGA platform is facilitated with the HES-DVM tool that provides new partitioning utilities and can convert ASIC clocks to FPGA-proof structures.

Assertions-Based Verification for VHDL Designs    
Assertion-based verification (ABV) is the use of assertions for the efficient verification of low-level design specification. These assertions could be verified by simulation and formal verification methods. SystemVerilog Assertions (SVA) standard provides powerful means to express both immediate and concurrent assertions as well as functional coverage constructs. Unlike SystemVerilog, VHDL does not include the concept of concurrent assertions (while VHDL assert statements being similar to immediate assertions in SVA). In this webinar, we will present various methods to implement assertions in VHDL designs as well as identify the strengths and limitations of each method. These methods include PSL (VHDL flavor), the usage of Open Verification Library (OVL) as well as concurrent assertions development using procedural code with assert statements. Play webinar
