In the current repository only a subset of the provided designs in the GRLIB are included, the recomended to use for simulation is the **leon3-minimal** (GRLIB/designs/leon3-minimal). In the current repository only a subset of the provided designs in the GRLIB are included, the recomended to use for simulation is the **leon3-minimal** (GRLIB/designs/leon3-minimal).
Different tests are included in the software directory, currently only for the leon3, in GRLIB/software/marcmod/leon3. In the design folder a mymake script is included which can be used to generate the test file for a program by executing: *./mymake $testname $testsize*. Testname ending with \_simd make use of the custom SIMD module. Different tests are included in the software directory, currently only for the leon3, in GRLIB/software/marcmod/leon3. In the design folder a mymake script is included which can be used to generate the test file for a program by executing: *./mymake $testname [-s testsize] [-p <in|out|all>]*. Testname ending with \_simd make use of the custom SIMD module.
The SIMD module and all future additions is found under GRLIB/libs/marcmod, although some modifications, identified in the file with *marcmod* are also found in GRLIB/libs/gaisler/leon3v3, specially the iu3.vhd file.

A working design for a Zynq Ultrascale+ FPGA can be found in grlib/design/leon3-xilinx-zcu102. To start the project execute *make vivado-launch*.
