Update cn0363 spi engine
Browse files Browse the repository at this point in the history
I replaced the SPI Engine connections in the ad738x_bd.tcl with the
spi_engine_create procedure found in the spi_engine.tcl script. Through
these changes, a more generic instantiation for the spi_engine can be
achieved. I updated the system_constr.xdc file and
created the cn0363_pmod.txt file.
