Web6 de abr. de 2012 · Introduction. Writing power intent for a design using the IEEE 1801 Unified Power Format (UPF) is generally an easy and straight-forward task. If the design will be optimized in a flat fashion (e.g. the entire design is optimized top-down in a single session), then writing the power intent is fairly simple. Situations such as being too rigid … Web11 de nov. de 2024 · 1 Answer. Sorted by: 8. I/Os of the top-level block are called port, I/Os of the subblocks are called pin. So get_ports and get_pins commands must be used accordingly. If the main clock is an input of the top-level block, get_ports is the appropriate command. For example: create_clock -name CLK [get_ports clock_main] ... Since …
