How can i make bidirectional pins virtual? :(

I am working on a design with bidirectional interfaces having an io count of more than 2000. I want to fit the design on a device and check its timings. But the max available pin count is hardly 1000...

why do you have more than 2000 bidirections IOs? how do you expect these to work on a real chip? Bidirs internally are converted to muxes. Bidirectional signals should really only be connected to a pin.

If they were coded as separate ins and outs (as they will end up as eventually anyway) then you could easily use virtual pins.
