Currently, XLS supports iverilog for simulating verilog module with a testbench. When simulating iverilog, the waveform of the testbench can be created for viewing by other open source tools (e.g. [gt…

iverilog expects the address of an array to be 2 bits larger than it should be. This can be observed well when converting the following code to verilog95 using iverilog:

Hi,
this verilog code assigning the same wire to two different ports with different direction through two levels of hierarchy triggers an assertion failure.
```verilog

If using the latest iverilog (as distributed with the OSS_CAD_Suite Icarus Verilog version 13.0), the test for user_project_example does not work. It works fine with Icarus Verilog version 10.3 (stab…

How to we implement the inter stage registers?
i.e IF/ID, ID/EX, EX/MEM, MEM/WB
In my view we can define them as type reg [:].
The store relevant outputs from previous stages in specific bit posi…
