Reality Is Often Disappointing

Installation

I realized a synthesizable top module to test the Sync module and Led Band Controller together. The goal of this top module is to simulate the ticks sent by the Hall effect and the optical fork sensors. But also to send data to the Leb Band Controller to simulate the DMA Controller. In the output, one can read SCLK, GCLK, LAT, SOUT, row_en[3:0] (multiplexing), turn_tick, n_rst.

With @nathan-claudel, we decided to synthesize and test it on the DE1-SOC. The output signals are exited on the GPIO1. Then I used a Saleae device to probe the signals.

Problems of the top module

First, we have to fix several issues due to the implementation of the top module.… Read more
