I replaced the SPI Engine connections in the adaq7980_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 configured the parameters for axi_pwm_gen and axi_clkgen according
to the results in the SPI_Engine_Timing_Computations Excel where I created a file
for adaq7980.
I created the adaq7980_fmc.txt file for generating the system_constr.xdc file.
I modified the system_bd.tcl, system_top.v, system_constr.xdc and Readme.md files.
Also I regenerated the Makefile.
This reduces the amount of boilerplate code that is present in these
Makefiles by a lot.
It also makes it possible to update the Makefile rules in future without
having to re-generate all the Makefiles.
