Hello. The following is a line from the MicroZed constraint file (microzed_7z010_master_XDC_RevB_v1.xdc).
Here is one line:
set_property PACKAGE_PIN T10 [get_ports{JX1_LVDS_0_N}]
Where is definition for "JX1_LVDS_0_N" and the other variables used in these constraint files?
Another example:
The Zedboard also has a constraint file (zedboard_master_XDC_RevC_D_v3.xdc) that also uses variables in this manner.
Here is one line:
set_property PACKAGE_PIN U11 [get_ports {OLED_VBAT}]; # "OLED-VBAT"
Thank you, Richard V
