« Prev | Next » Does the Aldec simulator have hierarchical referencing similar to ModelSim's Signal Spy? Description I would like to set a probe in my testbench to monitor a signal inside of the unit under test. How can I make a hierarchical reference to it? Solution We have similar feature named "Signal Agent". Basically you use Aldec's provided functions to map signals across hierarchical levels: Example: signal_agent (<source>, <destination>, <verbose>) Refer to the Active-HDL documentation (as shown below) for more details on using signal_agent command: Click on the Help tab. Select either PDF Documentation or HTML Documentation. Then, select either option: For Verilog: click on Using Active-HDL | Compilation | Verilog Compilation | Signal Agent For VHDL: click on Using Active-HDL | Compilation | VHDL Compilation | Utility Routines | Signal Agent Previous article Next article
