WebSep 18, 2024 · The blue path is the one that causes the violation. The main clock ( sys_clk onwards) is CLK100MHz_IBUF_BUFG. 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. WebDec 12, 2014 · I was running timing simulation using NCSim and due some issues the SDF annotation failed. However, I did not receive any timing violation as It happened before while using modelsim. Receiving violations is a sign that there are delay information. The delay info exists in the library models I compiled. hikvision 4mp ip poe dome cameraWebWhat appears to be happening above is that during back-annotation, it can't find the setup and hold timing checks in your verilog model. If this is what's happening, it is important, because even though the simulation is passing, it may be passing without performing setup and hold timing checks. diablo over 11 years ago small wineries near me
