WebApr 14, 2024 · It sounds like you want to implement a fractional clock divider with a digital circuit. Since the division of the clocks is a fraction, the output clock will jitter between two clock periods (in your case between 6 and 7 periods of the 100 MHz clock), but the average will be 100/16=6.25 periods long. http://www.sunburst-design.com/papers/CummingsSNUG2000SJ_NBA.pdf http://www.testbench.in/TB_16_RACE_CONDITION.html brevard nc business for sale

WebJan 5, 2024 · Assigning clk_1_5 = rclk and then reassigning it in the case statement can generate a glitch. This will be enough to trigger the @ (posedge clk_1_5). You can fix that by removing the initial assignment and adding a default clause in the case statement. WebDef an internal signal in this case. Really in 99.9% of cases. Assign outputs at the end. This way, clk_div is never read, only assigned the value of an internal signal (clk_div_internal), which can be read.
