Creating a single pin per iterm instead of one per mpin #31

Closed ax3ghazy closed 4 years ago

Hello,

Currently, multiple Pins are created per PORT (mpin) of a PIN (in LEF terminology). This causes the sink-source check fail for any macro/cell that does have multiple ports on a pin. I have fixed it, so now all shapes across different mpins of an iterm are first merged then only a single Pin is created per iterm. All tests on openroad of OpenROAD are passing with this change.

Please let me know if I missed or misunderstood something.

Thanks.
