SRAM 160MHz, impedance matching

Hello, In my board I have one SRAM directly connected to a FPGA Cyclone 2. I am working at 160MHz. But sometimes I have an strange behavior when reading the SRAM. I am sure is something ab...

Reviewing your posts, the only information I find is you "sometimes have a strange behaviour". That's not actually specific. You also didn't give any hint to determine, if impedance matching can be an actual problem at all (e.g. in terms of trace lengths). Now you reported, that you exchanged some pins and see "drastical changes". I don't know how to give suggestions based on this amount of information.
