WebMar 18, 2013 · The short is that, for cascaded plls, one cannot use derive_pll_clocks in the .sdc file. 'create_generated_clock' is necessary. To help with this, they pointed to AN471 pg13-15 for creating the generated clock for a switchover PLL. They also suggest the following steps to help create the 'create_generated_clock' syntax. 1. WebWe remove the ‘divide-by’ option and use the edge values of 1,3,5 to define the new clock. This says, that at ‘1’ edge of master_clock, the first rise edge of gen_clock arrives. At … WebJan 30, 2024 · The first thing is to identify how many divided clocks are needed out of a master clock. You could need divided by 2,4,8 for example. The number of counter bits required to implement this follows the rule: Say, the highest divisor is 8 from the above example, you’ll need 2^n>8. In this case, n = 4. For this case, counters can be any type … dr nancy chang providence bridgeport
