xio2001 PCI SW driver does not receive any interrupt

lively li

The problem we are observing right now is that interrupt do not seem propagated from the INTAN input line of the bridge to the PC.Even if INTAN is asserted low, our PCI SW driver does not receive any interrupt.The PC to anormanl receive interrupt.

Here is the schematics.

This is the reason.

We tie iINTA to the wrong AD pin .We try to tie connect INTA and INTB with the same pin AD16, it OK.
