Description

From the original program:

"Hardware bugs in systems on the scale of a modern large VAX are both probable and painful: probable, because of the size and complexity of the design; painful, because of the long lead-time required to obtain a new gate array or custom part. Simulation is one way to find and fix bugs before hardware is built. Simulation offers near-perfect visibility of the hardware (no signals are buried inside chips) and rapid turnaround time for bug fixes, but runs extremely slowly compared to the real thing.

This talk will descirbe experiences in using gate-level simulation of an entire VAX CPU designed in Littleton. The size and speed of the simulation models will be addressed along with the bug-dinsing methods used and the results ni terms of bugs found and bugs missed. Useful lessons for future projects will be given."
