Simulating TTL Circuits

December 24, 2022December 23, 2016 by Frank DeCaire

Summary I’m going to continue with my logic simulator project in this post. This project has turned into a serious obsession, ahem, hobby. My final goal is to be able to simulate a full computer circuit. TTL Logic As I’ve mentioned in my previous posts, there is a wiki page for TTL logic that lists … Read moreSimulating TTL Circuits

JK Master/Slave Flip Flop

February 14, 2019December 10, 2016 by Frank DeCaire

Introduction I’m sure readers are becoming bored with Flip Flops by now, but bear with me. The previous JK flip flop was a simple 4-NAND gate device, this circuit is the standard two flip flop device that is more stable when used in toggle mode. The Circuit The Master/Slave flip flop circuit is a bit … Read moreJK Master/Slave Flip Flop

JK Flip Flop Simulator

February 14, 2019December 3, 2016 by Frank DeCaire

Introduction I’ve been working on a simulation of the JK flip flop for quite some time now. I had to tweak my algorithms a bit to overcome problems with an unstable condition that I’ll discuss in this blog post. Handling Unknown Inputs One of the problems with circuits that contain feed back connections is that … Read moreJK Flip Flop Simulator
