WebDec 14, 2012 · It depends strongly on your design if it is necessary or not. Some timing violations can be ignored, e.g. the hardware sets an register-bit but it doesnt matter if this bit is really set in the next cycle or some cycle later. In that case you're allowed either to set a false path or a multicycle path. Dec 14, 2012. Web1. Intel® FPGA AI Suite Getting Started Guide 2. About the Intel® FPGA AI Suite 3.
