Web5.5.6.4.6. Internal FPGA Path Timing Violation. If timing violations are reported at the internal FPGA paths (such as _usr_clk or _phy_clk_* ), consider the following guidelines: If setup time violation is reported, lower the clock rate of the user logic from full-rate to half-rate, or from half-rate to quarter-rate. WebDefinition of false path: A timing path, which can get captured even after a very large interval of time has passes, and still, can produce the required output is termed as a false path.A false path, thus, does not need to get timed and can be ignored while doing timing analysis. Common false path scenarios: Below, we list some of the examples , where …
