How does OpenLane read the Value of pitch, it seems incorrect. Pitch should have been the center to center distance of 2 adjacent metal lines. However Openlane is skipping 1 metal line in PDN for pitch. It is taking the value as center to center distance between power/ground metal lines. @User Any idea? I have attached the snippets

This values comes from PDN.cfg. Do create custom cfg file and over-write by defining PDN_CFG env variable from config.tcl

if you have 1 power domain, you'll have power and ground alternated. So the pitch is between the gnd and gnd or vcc and vcc

But shouldn't pitch be between adjacent straps, rather then

gnd -> gnd

and

vcc -> vcc

?

🤷

I remember it was between adjacent straps in the beginning, I don't know when it was changed to this and why
