How could I assign IO type during " Create Pins from Labels" option

Anklon

When I import .gds from INNOVUS , there is no pins but labels. So I have to use "Create Pins from Labels" tool to place pins. But all the pins IO type are "inputoutput". How could I define IO types so that, I don't have to make it manually after using "Create Pins from Labels" . How can I do that? or I'm missing some command during PnR in INNOVUS  that I'm facing this problem?

Thank You for your time :)

    OK - hopefully this question will remain this time - I saw it a few days ago (twice) and then it kept vanishing before I had a chance to answer it.

    GDS (Stream format) is not a particularly great way of transferring connectivity information between tools as it doesn't really support connectivity. So there's nothing for it to know the pin direction (not sure why it necessarily matters, but nevertheless there's no way of knowing what the direction is supposed to be). A better solution would either be to go via OA directly (which may involve some flow changes on your part) or exporting LEF from INNOVUS and importing the LEF. LEF also contains the pins and the pin directions, so there would be no need to recreate the pins after import.

    Regards,

    Andrew.
