Constraint based parameterized cell

A linear programming engine solved all constraints

• Define & Match Object Template

For some common layout patterns such as via and transistor-gate, the system can match the patterns on the layout and put the constraints on the matched patterns. The system-defined constraints are design constraints., for example, the gate width/length of transistor, the cut width/spacing/enclosure of via, etc.

• Set User Constraint - Edge

Users can define constraints on the existing shapes/instances. The constraints can also be parameterized. The constraints are user constraints.

• Set Rule Constraint

GOLF-Pcell carries the process design rules to assure that the layout generated is design rule correct. This rule constraints approach can reduce the tape-out cycle for process change. That's why AnaGlobe claim GOLF-Pcell as a universal Pcell.
