When simulating verilog output using Icarus, is there a way to include FPGA hardware features such as RAM in the simulation?

I'm new to FPGA, and have started out with an iceBreaker board using the ICE40UP5K chip. I'm aiming to make a LED display driver, driving something similar to HUB75 used on popular display modules. I've been able to simulate waveform generation, and…

How to generate seasonal time series data in positive value using sim.ssarima in R?

I want to make X-13 ARIMA-SEATS simulation using seasonal time series data that generate from package 'sim.ssarima'. But in X-13 ARIMA-SEATS require the data must be non-zero and positive value. Whereas 'sim.ssarima' generate random value (positive…

Increasing model simulation speed with big number of agents/transporters Anylogic

I've a question. In my model I want to model patients/employees in a hospital environment as agents. Due to the big amount of patients/employees in the hospital (>4000), my model runs very slow (which is logical, I know). Because I want the patients…

Count the times a transporter is blocked by another transporter

If you have two different transporter types in your model. And you want to have a variable that counts the amount of time they are close to each other (say within 0.5meter) and blocking each other. Is there a way in anylogic to code this? So that…
