SB_IO and SB_GB_IO PACKAGE_PIN connected to the same port cause fatal error #114

Non-reduced testcase: glasgow_6kkz18rn.zip. Caused by clk_if port.

Also, the error message points at the end of blif and is thus useless.

This is not a legal design as far as I know. SB_GB_IO has all of the ports and parameters of SB_IO too, and they should be used instead of adding another SB_IO.

You're right. Sorry for the noise.
