Sls : Switch-Level Simulator User's Manual

INTRODUCTION This manual is meant as a guide to users who want to simulate their network with the sls simulator. The acronym sls stands for Switch-Level Simulator, and the simulator can be used for simulating the logical and timing behavior of digital MOS circuits. In the simulator transistors are modeled by grounded capacitors and a switched resistor. Each node in the network has a logic state O, I or X (for unknown), and each transistor has a state on, off or undefined. Many characteristics of MOS circuits can be modeled accurately, including: ratioed, complementary and precharged logic; dynamic and static storage; pass transistors; busses; and charge sharing. Because the simulator performs local-event-driven simulation, large networks with thousands of transistors can be simulated in a reasonable time. The sls simulator is capable of simulating a MOS transistor
