or2 standard cell family

2-I/P OR gate
or2 symbol
2 I/P OR gates designed with large (v0 version) and small (v4 version) input stages, and the or2v7x2 which uses an N transistor pull-up on the output to speed up the rise delay. This leads to a temporary high short circuit current which is about 30% higher than the equivalent or2v0x2 cell. The stage effort is 1.5 for the or2v0x05, 1.8 for the or2v0x1, 2.2 for the or2v0x2, 2.4 for the or2v0x3, 2.6 for the or2v0x4, 3.0 for the or2v0x8 and 4.0 for the or2v4x1. The v0 cells are optimised for speed with typical wireload values, while the v4 cell is optimised for a zero wireload capacitance.
The nd2ab cells do the same function faster but use more power.
