#461 Question about maximum current in Rsil
Issue created by

Hi In the docs there is no description, about how much current can Rsil drop.

It is only refers to 2.9, but 2.9 is for Rhigh. I think this reference is from an older version..... It said limited by contacts, but in the layout there is always only one contact per pin, doesn't matter how long/wide is the resistor. Here is a screenshot from Klayout with w=5u/l=0.5u and w=0.5u/l=5u

Both resistors has only two contacts (one per pin) Thank you in advance. Ghaith.
