The search engines are failing me.
Dear Lazy Web:
If I wanted to enumerate the hierarchy of a design at the beginning of a cocotb test bench, how would I do it? (I'm aware of _discover_all(), but can't figure out how to iterate the results to print them.)
Extra credit: How do I get an interactive debugger to break within the cocotb python code if I call cocotb from pytest? It seems to run the pytest code in the debugger, but not the cocotb code.
#cocotb, a #freesoftware cosimulation testbench environment for verifying #VHDL and #SystemVerilog #RTL using #Python, is part now of #guixscience channel. It may be used as any other #guix package with a simple
guix install python-cocotb
This means too that pre-built substitutes are available online 🥳.
@Tathar I would like to see a good one too. I'm all my years doing #vhdl and #verilog for a living the best test benches I ever have seen have just read in golden vectors and wrote out result vectors so they could be checked by an external script. We now use #cocotb and I'm starting to like it. I don't feel an hdl is a good match for testbench work. Maybe for a fixture layer connecting hdl blocks. But testbenches are not hardware. Why would we expect an hdl would do well for it?
Implementing HDL verification using #UVM is annoying and tedious. So #cocotb seems to be the right choice. #FPGA #Python #systemverilog #VHDL
@remi Yeah my whole group gave up on mathworks (and Microsoft). We do everything in python now with boost c++ for some bits (on linux). No more dealing with license servers is great. We stimulate on a cluster of machines now and never worry about running out of licenses. It's great. Now when we can get rid of #modelsim we will be ~100% #foss tool chain. #ghdl and or #cvc with #cocotb is close but not quite. Xilinx #vivado encrypted ip cores are a problem that can only be avoided by saying no...
I have a nominally working simulation of a PI controller for the quadrature current in my scratch designed #fpga motor controller. Simulated in #ghdl and #cocotb. And the #xilinx ISE build fits! So I'm back to looking at the blown up hardware. Just pulled the scratch designed motor controller out of the Ice Cream Truck... I don't see a blown FET yet, but I saw a flash and pop the last time I worked on it, so I know it's in there somewhere. Race is on May 20th in #chicago Come out and help me!
Yay, my #riscv implementation in spade is now far along that I can run ISA tests.
#cocotb makes it really simple to generate test cases from the compiled elf files in https://github.com/riscv-software-src/riscv-tests

In french, if we pronounce «cocotb» without 'b' it sound like #cocotte which is a casserole.
Then if we look for cocotb book on amazon we get this :)
