Access to pg_pins' timing lib

[leolin1206]

Hello,

I hope you are doing well.

I tried to access the timing library for the pg_pins but I wasn't able to find any information from the libraries. I was able to find specific input/output pin timing info but not the general pg_pin timing info. Does anyone know any access to the timing info for pg_pin timings?

pg_pin ("VGND") {
pg_type : "primary_ground";
related_bias_pin : "VPB";
voltage_name : "VGND";
}
pg_pin ("VNB") {
pg_type : "nwell";
physical_connection : "device_layer";
voltage_name : "VNB";
}
pg_pin ("VPB") {
pg_type : "pwell";
physical_connection : "device_layer";
voltage_name : "VPB";
}
pg_pin ("VPWR") {
pg_type : "primary_power";
related_bias_pin : "VNB";
voltage_name : "VPWR";
}

Thank you very much for your assists and directions.

Leo

The Liberty timing model does not support timings on pg_pins. What is your use case for this? Generally this kind of information would never be needed in a digital flow.
