Hi @tnt: Im starting a new thread on pin placement since the thread on running the counter example has become too long. As per the link you provided: https://openlane2.readthedocs.io/en/latest/reference/pin_placement_cfg.html I did the following: • Create the attached pin_order.cfg file and placed it in my rundir. • Updated my config.json file to include the following: "FP_PIN_ORDER_CFG": ["dir::pin_order.cfg"] When I run however, the tool errors out complaining it can't find the pin_order.cfg file, which is odd since, as shown in the attached screenshots, it is clearly there. Regarding power and gnd pins. They are not in my .v file (also attached) so how are these dealt with by the tool? Thanks

@Diarmuid Collins I believe the

FP_PIN_ORDER_CFG

variable is a scalar value instead of a list. Can you try

"FP_PIN_ORDER_CFG": "dir::pin_order.cfg",
