> Type of pins > > Why does it warn about > output <--> input/output > input/output <--> pwr Because drc2 can't check if an input/output pin is really an input or an output (or even both, depending on the design). It gives you warnings (not errors) about this, so you can check by your own. It tries to catch errors like connecting an output to another output, or an output to a power rail. Drc2 is not perfect, and has limitations, but it's all we have by now. > The "ERROR" is a lm7805's output (U3:3) connected to other pins of > type pwr. How do I make it accept that? There is no concept like "pwr in" or "pwr out", so just giving it the pwr pintype should be ok. [snip] > The "unconnected pins" can be left unconnected, how can I make it > accept that? If you connect them to a special nc (no connection) symbol, drc2 will ignore them.
