Web18 Jul 2024 · Origin of setup and hold time: In broader terms, any circuit that stores value has a back to back inverter or some other back to back gates to hold the value. However such a circuit is not ofmuch use, unless we can control the value that's stored in this back to back inverter. This is done via a signal to enable or disable the write, and ...

Web4 Nov 2016 · The -max and -min values state what the external max and min delays are to this external register. Looking at -max 3.0 since it's easier to understand, this says there is a 3ns delay to the external register. Since we have a 10ns setup relationship, then the FPGA must get the signal out dout[*] ports by time 7ns or it will fail setup.
