Have you considered making an ASIC of your design? https://efabless.com/open_shuttle_program

It's likely too big for those programs - I am (just now) starting a build with the Open Lane/Sky tools not with the intent of actually taping out but more to squeeze the architectural timing (above the slow FPGA I've been using for bringing up Linux) so I can find the places where I'm being stupidly unreasonable about timing (working on my own I can't afford a Synopsys license)

Gotcha. Did you run into any issues with yosys given that it has limited system verilog support?
