IO for ECP5/ECP5-5G\u200B: Does ECP5 have a dedicated reset IO?
ECP5 can utilize any GPIO as reset on their design, In order to utilize a dedicated routing for the reset, users may use the GSR (Global Set/Reset IO) resource. The primitive can be utilized either through inference or design instantiation. If it is utilized through inference, the tool will select an asynchronous active low reset signal with the highest fanout. You can also select a GPIO directly for your GSR.
