Thanks for the ideas. Looking at the hdl generated by sysgen I see that the code mostly instantiates a few components like lut2, muxcy, fde and IPs like block memory generators (the report generated says that the only IPs used are brams, counters and adders). I think one possibility to improve the simulation process would be to generate wrappers that imitate the behaviour of those primitives and the IPs, and use external simulators like verilator which generate C++ models from verilog code. Or to use cocotb which is easier but slower (I think it should be faster than matlab anyways haha..) Like I am out of time, I would try it in another opportunity. But I share the idea to see if someone sees any problem with that path.
