5796 - MachXO2, MachXO3: What is the value of tSUD_PFU and tHD_PFU in the XO2/XO3 series?
Starting from the XO2 device, many of the timing parameters were removed to simplify the datasheets, as there were too many speed-grade and package data to list.
To simplify, the value for this kind of parameter can be obtained from the trace report. We recommend creating a simple test design using the target device with a reasonable clock constraint. The map and par trace reports will include all delay paths and timing arcs. Parameters such as tSUD_PFU and tHD_PFU are easily extracted by examination.
