[SOLVED] - How to fix intra clock timing violation

WebTransition violations can be fixed by either by upsizing the driver, or perhaps splitting the net by insert a buffer which would effectively split the load driven by a cell and hence improve transition. Buffer insertion would also help fixing max_capacitance violations as well. After clock DRV fixing, you can perhaps do a data DRC/DRV fixing. WebSep 18, 2024 · This is the Basys 3 main 100 MHz clock. df is a debounce filter. cd and cds are clock dividers. As you see, cd is clocked by sys_clk and cds by cd/clk, which is sys_clk divided. The reset signal comes from an FPGA button, however it is passed through a debounce filter. Therefore, the rst signal depicted above will be synchronous with …
