HDL built-in variables

[vanjazeric]

Hello,

I am working on NandToTetris projects these days, and I found something interesting, that I would like to know. In some projects, I needed to use '1' or '0' as input at some gates (or 16-bit '11..111' or '00..000') and I used to make it using some logic gates such as NOT and OR gates to get the behavior. I know we should use as least as possible gates, so I am wondering if there are variables, such as bool in C/C++ (true/false) to represent '1' or '0' in order to reduce the number of gates.

Best regards,
Vanja.

Look at the documentation for the HDL language in Appendix A. Specifically, Section A.5.2.

Thank you. I found exactly what I wanted.
