A new Digital Simulation Tool

[monsonite]

A friend put me onto this new open source digital simulation tool.

https://github.com/hneemann/Digital/releases/tag/v0.23

It's very similar to Logisim which is now no longer supported.

It has an extensive library of TTL devices and memory - so it should be possible to simulate the Gigatron.

I decided to spend a day modeling some of the Gigatron ALU and instruction decoder.

The simulator allows a very slow clock to be applied, and the use of LEDs to indicate the output of the various registers. It's very easy to see the accumulator count up or down - if ADD or SUB has been selected.

Here is the op-code decoder and it's diode ROM. The rest of my simulation models will be placed on my Github repository here:
