i am developing pcb with part cy8c4126axi-m443 (44 pin TQFP ) part. in psoc creator in design file(.cydwr) pin number 1 is showing black with label nc(all other power pin is hilighted with green colour other than this one). while in data sheet pin 1 is labeled as VSSD. what should i do? should i connect it to ground or left unconnected on pcb?
PSoC creator shows the pins from the componentn / design perspective. For that, GND pins are not really interesting (you don't connect any of your components to them). So follow the data sheet.
