Aha! With help, I've got Riviera-PRO running in Linux (Windows + WSL). I've got doing a Mode A transmission. I just need the final piece to connect the two and then I've got full cosimulation!

Well appears as if there's no concept of time in . Everything is sample based. It's understandable but means the first helper module I think I will need to write is a sample counter though to provide other modules with a concept of time.

@Tathar Well, for avionics test, I do signal receipt and correlation and demodulation, then the other side modulation and transmission in . However that's not what's making me walk through gnuradio. Apparently has a block that lets you use in co-simulation with -PRO. If I have an easier to work with signal generation or signal analysis tool, it would aid verification.

I've written signal toolbox stuff in VHDL for simulation, but I'll be honest, it's a pain in the ass to work with: tedious to construct and a pain in the ass to modify (depending on what you want.). There's a possibility gnuradio is easier (though also a possibility it is not. I've not yet got through a tutorial that actually gave me a sense of how the tool deals with time. I think it probably doesn't which means if I need a particular timing I will be sample counting and it'll make it anchored to sample rate when it'd just be nicer to wait X microseconds and then modulate.)

Progressing further through the tutorials. I'm not sure I"m yet to the point of knowing how to apply time based modulation to the signals, but possibly getting closer.

Playing around with GNU Radio, a software suite I had no idea existed until the other day. Apparently there's also (when I get more proficient with it) a way to pipe the output of this into Riviera-PRO for FPGA simulation. I have LONG wanted a better signal generation sandbox for verification and this could potentially be very neat. Just a lot of baby steps to learn it, it's a beast of a software and I need to be able to write modulation schemes for SIF, Mode S, et al

Finally got the NCO core to properly sim in Riviera simulator. I really hate cores, especially encrypted ones.
