I’d appreciate some help on the methodology of debugging a gate level verilog design synthesized by yosys. The gl verilog is 200K+ lines and consists of only standard cells. I’m detecting a Hi-Z input (disabled tristate inverter output) to a complex logic gate and I want to view the surrounding signals. Is there a way to extract the minimal logic cone for a given signal with yosys or some other tool?
Copy code
select c:U11872 %ci10:-sky130_fd_sc_hd__sdfrtp_1[D]
Will print the input cone of instance
U11872
to a depth of 10 while not tracing the
D
connections of
sky130_fd_sc_hd__sdfrtp_1
.
