WebI look into the RTL schematic together with timing analyzer and tried to understand why there are such large number of logic levels and fan-out signals. I found the followings are consuming sufficient large amount of delay in the data path: a) if/else statement / switch-case on pos, offset etc. b) maths calculation (e.g. adder) on pos, offset. WebAug 14, 2015 · By default, the software creates one generated clock at the pin by using the fastest clock present on the source pin as the master clock. However, use the -add option to specify a different clock name for each generated clock when used with the -master_clock option. Subsequently, you can use this clock name for setting other …

WebIntroduction to C++ hash. In C++, the hash is a function that is used for creating a hash table. When this function is called, it will generate an address for each key which is … WebJun 23, 2024 · The tool propagates clocks through CK->Q arcs of the flop generating the selection back to master clock which becomes worst case latency. There's an option -combinational with create_generated_clock which will only trace through combinational arcs. If your scenario is similar to what I've described having the combinational option … gifting on crypto platforms
