Hmmm... maybe I'm going about this the wrong way. Would it make more sense to get rid of the LA on that side, move the sdram chip as close as I can to the FPGA, and use something like chipscope to monitor the signals? I've got both SPI and addr/data connections to the MCU on the other side to get the data out. > This is why the mictor connector exists. Yeah, but that's pushing the project outside the effort I want to put into this board - basically, it's a one-time board to try some things with. > Here's another idea. Instead of the LA, use a scope My scope is nowhere near fast enough for that. The LA is 500 ms/s or can be externally clocked up to 200 mhz. The scope is only 32 ms/s. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
