So I made this thing [attached I hope]. It's a Gigatron laid out in SimulIDE https://www.simulide.com
It has been a tough job debugging but I got it to the point where It runs through the boot process and lights up the blinkenlights in order and eventually jumps off to $1200 to start loading things,
I built it to try out a few ideas and to get a good understanding of the Gigatron architecture before I start changing things. I'll probably have to start making my own tiny test ROMs to try out specific features

Re: Circuit simulator
I just was looking for a nice simulator. Still have to check if NGspice within KiCad works, but a working Gigatron is already good enough for me.
Re: Circuit simulator
At what speed do you run it? (use version 0.4.15-SR9) The blinken lights do not light correctly.
Re: Circuit simulator
I run it at 100Hz. The first led Lights up after about a minute. Then there is quite a long wait (15 min) while it does the entropy gathering code. You should be able to see X and Y count through the full range of memory while it does this.
