running cocotb inside a virtualenv

I currently do have trouble to run cocotb inside a virtualenv. I can not find any example to get it running. Is it even possible?

I think one of the problems is. cocotb-config --makefiles It always points to the system installation. Even I call the venv Makefile.sim @. $(VENVACTIVATE) && include $(VENVDIR)/lib/python3.8/site-packages/cocotb/share/makefiles/Makefile.sim The cocotb-config is used multiple times in other e.g. Makefile.verilator. So it would need quite a lot of changes to get around this.

• the cocotb version used: 1.6.2
• the operating system and version (32/64 bit): 64bit
• the simulator and version (32/64 bit): Verilator 4.106
• the Python version, and where it’s coming from (e.g. system, Anaconda, self-installed, …): system 3.8

No currently I do use echo “$SHELL” -> /usr/bin/zsh

Check your .zshrc.

If cocotb is installed where ever but cocotb-config will always give the same results.

That’s because when you call cocotb-config it’s finding the cocotb-config you have installed in ~/.local/ first, because it comes first in $PATH. This causes cocotb-config to output the makefiles in the cocotb install in ~/.local/ rather than your virtualenv. The reason that ~/.local/ is showing up first in your path in front of your virtualenv is likely because you are prepending it in your shell’s rcfile which is run every time a shell is exec’d.
