Constraints file for I/O Carrier Card

Question

Isn't there a constraints file available for the I/O Carrier card with MicroZed? I just found this: Z7010 or Z7020 MicroZed with MBCC-BRK-PCB-A_v2.xdc but this is for breakout board.

The Master Contraints file has a line for each available signal. To generate a constraints file for your design you will need to either comment out or remove any lines related to pins/signals that you are not using. In other words, if your design only used two external signals on pins U14 and U15, you would need to comment out or remove all of the "set_property PACKAGE_PIN.." lines EXCEPT for the two below: set_property PACKAGE_PIN U14 [get_ports {LED0}]; # "U14.JX1_LVDS_10_P.JX1.41.LED0" set_property PACKAGE_PIN U15 [get_ports {LED1}]; # "U15.JX1_LVDS_10_N.JX1.43.LED1" Then, in your design, you would need to assign those signals the names "LED0" and "LED1" or change the signal names in the "set_property PACKAGE_PIN.." constraint lines to match your signal names. At the end of the Master Constraints file there are commented example "set_property IOSTANDARD " constraints for each I/O bank. Un-comment one for each I/O bank that you are actually using and set the appropriate IO standard. As discussed in the comments above these lines make sure they are after any package pin definitions you have in your constraints file. -Gary
