hi all , i am new subscriber, i have been reading all ur mails and found very helpfull in designing. i am designing board with plx chip with pci slot, the specification given that pci to plx signal should be small as possible , but clock signal must be 2.5 inches, i have routed clk in serpentine manner(tunning method) to match length, but i read somewhere that clk signal should be straight as possible, but how it could be possible to have matched length without tunning. or tunning method will do for clock, suggest me best option. thanks in advance. rishi.
