It seems that I should be able to tell Vivado that I have a microzed board, and then change the Zynq from a 7z010 to a 7z020. This way I have all the parameters correct with a minimum of effort. I tried this by manually changing a configuration file, but then Vivado has a snit when I synthesize:
WARNING: [Project 1-153] The current project part 'xc7z020clg400-1' does not match with the 'EM.AVNET.COM:ZYNQ:MICROZED:E' board part settings. The project part will be reset to 'EM.AVNET.COM:ZYNQ:MICROZED:E' board part.
INFO: [Project 1-152] Project part set to zynq (xc7z010clg400-1)
Is there any way I can get all the microzed settings without doing an involved manual operation to copy them?
"board awareness" files seem promising, but the ones I've found don't seem to have nearly enough information (such as DDR memory trace lengths)
