### Note:
# - input clock transition and latency are set for wb_clk_i port.
#   If your design is using the user_clock2, update the clock constraints to reflect that and use usr_* variables.
# - IO ports are assumed to be asynchronous. If they're synchronous to the clock, update the variable IO_SYNC to 1.
#   As well, update in_ext_delay and out_ext_delay with the required I/O external delays.
