Model division of cancer cells on a grid

I have a 5000x5000 grid, and I'm trying to implement a simple model of cancer division in MATLAB. Initially, it picks a random point (x,y) and makes that cell a cancer cell. On the first iteration, it divides - the parent cell stays in it's place,…

Is there a reason to initialize (not reset) signals in VHDL and Verilog?

I have never initialized signals. That way any signal missing a reset or assignment would be unknown or initialized. In some reference code they have initialization. This defeats what I wish. Also since intialization isn't synthesizable, there could…

Water simulation with a grid

For a while I've been attempting to simulate flowing water with algorithms I've scavenged from "Real-Time Fluid Dynamics for Games". The trouble is I don't seem to get out water-like behavior with those algorithms. Myself I guess I'm doing something…

Simulating a CPU design written in Chisel

I've written a single-cycled CPU in Chisel3 which implements most of the RV32I instructions (except CSR, Fence, ECALL/BREAK, LB/SB, which may be included later). The instructions are currently hard coded in the instruction memory, but I will change…

Is it possible to create a simulation waveform from yosys output

I've found simulating using iverilog to be a less than suitable method, I can simulate designs that won't synthesise and conversely designs that will not only synthesize but also work as intended on physical hardware, won't synthesise with iverilog…

How to stop a simulation by timeout?

I have manageg to implement a simulation timeout in VHDL. If processes are running longer the MaxRuntime they get 'killed'. Unfortunately, this does not work the other way around. If my simulation is finished before MaxRuntime, everything is waiting…
