In trying to fix a bug with Ethernet MAC/phy operation, I came across AR
24494 which mentions "silicon rev CES4 or later". How can one determine the silicon rev? I have two different parts marked as follows:Virtex4 XC4VFX12 FF668AGQ0513 -- does Q0513 mean 13th week of 2005? DD15537A
10C-ESVirtex4 XC4VFX12 FFG668DGQ0733 DD1466805A
10CMy guess is that the first part is pre CES4 and the last part is post CES4. Can someone explain the system here? I thought I had seen Peter explain the sequence of silicon rev numbers here before, but I can't seem to find it in the archives or on xilinx.com.
thanks,
