Welcome in the forum.
You cannot put properties into a component that the "normal" design cannot provide. Components are just a shortcut for a repeated design.
Creating components for PSoC1 is something complicated, did you already consider using a PSoC4 or PSoC5 ?
Thanks for your support. When I readed about PSoC I thinked that it was like a microcontroller with a PLD inside, so I could make any change in PSoC PLD and integrate with PSoC microcontroler. But seems that Digital Resourcer PSoC1 are closed to end user. PSoC1 is perfect to my project because I need few IO, the PSoC4 and PSoC5 has many pinouts.
Do you know how to access DBB resources of PSoC1?
