Standard Cell Realization for the Mentor Graphics CAD Environment

A common way of designing microelectronic circuits is by the use of standard cells. In advance systems the circuit can be read from a schematic diagram and the computer will select and place the cells and layout the signal paths automatically. In order to do so the computer needs a representation of these cells and a description of the routing design rules. The format and content of these descriptions were investigated for the Mentor Graphics IDEA system and a procedure for building libraries of standard cells was developed. The related data files were then developed to allow the creation of a library of standard cells for the RIT NMOS process
