Is this the same software Curious Marc is using to emulate a DSKY/AGC for their apollo comms project? Or are they using something custom spun up to support the hardware they are working on?
"Mike Stewart has developed gate accurate FPGA replicas of the AGC and its test hardware. It represents a massive amount of work. If you are Mike, you can use it to fly the real missions, and simulate every signal in the AGC. Making this work is not for the faint or heart and requires intimate understanding of the AGC hardware and software. We offer no instructions and no support."
For the communications project specifically (and also a couple of other projects we have going on), I combined the FPGA AGC and the Monitor into a single design that runs on a Digilent Cmod A7-35T: https://github.com/thewonderidiot/cmod_agc
It's a lot cheaper and more accessible in this form, and much easier to integrate into projects that need AGC stand-ins.
Aside from the FPGA design though, yeah, all of the AGC software and the assembler is in the VirtualAGC repository.
Mike Stewart, that is the one with the most in depth knowledge about the AGC on the Curious Marc channel, is also one of the main contributors to this repo, so I guess so.
