WebDec 1, 2016 · set_max/min_delay is basically telling TQ what the setup or hold relationship should be. For example, if you have a 10ns clock and you wanted to say a particular path should have 2 cycles, you would normally do a multicycle -setup 2 and multicycle -hold 1, to make the setup relationship 20ns and hold of 0ns. WebJun 25, 2024 · Hello everyone, I have a design where on the top level I have a clock signal as a port and I want to make sure it arrives with a delay at a specific pin inside the hierarchy.
