A new Digital Simulation Tool

Post by monsonite »

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


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:
