Copy code

make user_proj_example

with default openlane/user_proj_example.v does not seem to need a pdn.tcl file With my verilog in openlane/user_proj_example.v it requires one. Not sure why? So if I copy openlane/user_project_wrapper/pdn.tcl I get

Copy code

[CRIT] [PDNG-9999] Unexpected error: Error: pdn.tcl, 18 can't read "::env(_WIDTH)": no such variable

same for env vars _VDD_NET_NAME and _GND_NET_NAME. How should I define them in config?
