Instrumentation of a NASAP Subroutine

A program for the detection of loops in a circuit analysis is presented. This program, a FORTRAN routine entitled LOOPS, is the heart of the UCLA version of NASAP (Network Analysis for Systems Applications Program). In order to study the execution of LOOPS, it has been subjected to an automatic instrumentation process developed at UCLA. Results of this analysis are presented showing the most time-consuming portions of the routine and other performance measurements.
