# FPGA Startup and Configuration Guide
OPAE Environment Setup
----------------------
$ source /opt/inteldevstack/init_env_user.sh
$ export OPAE_HOME=/opt/opae/1.1.2
$ export PATH=$OPAE_HOME/bin:$PATH
$ export C_INCLUDE_PATH=$OPAE_HOME/include:$C_INCLUDE_PATH
$ export LIBRARY_PATH=$OPAE_HOME/lib:$LIBRARY_PATH
$ export LD_LIBRARY_PATH=$OPAE_HOME/lib:$LD_LIBRARY_PATH
OPAE Build
------------------
The FPGA has to following configuration options:
- DEVICE_FAMILY=arria10 | stratix10
- NUM_CORES=#n
Command line:
$ cd hw/syn/altera/opae
$ PREFIX=test1 TARGET=fpga NUM_CORES=4 make
A new folder (ex: `test1_xxx_4c`) will be created and the build will start and take ~30-480 min to complete.
Setting TARGET=ase will build the project for simulation using Intel ASE.
OPAE Build Configuration
------------------------
The hardware configuration file `/hw/rtl/VX_config.vh` defines all the hardware parameters that can be modified when build the processor.For example, have the following parameters that can be configured:
- `NUM_WARPS`: Number of warps per cores
- `NUM_THREADS`: Number of threads per warps
- `PERF_ENABLE`: enable the use of all profile counters
You configure the syntesis build from the command line:
$ CONFIGS="-DPERF_ENABLE -DNUM_THREADS=8" make
OPAE Build Progress
-------------------
You could check the last 10 lines in the build log for possible errors until build completion.
$ tail -n 10 <build_dir>/build.log
Check if the build is still running by looking for quartus_sh, quartus_syn, or quartus_fit programs.
$ ps -u <username>
If the build fails and you need to restart it, clean up the build folder using the following command:
$ make clean
The file `vortex_afu.gbs` should exist when the build is done:
$ ls -lsa <build_dir>/synth/vortex_afu.gbs
Signing the bitstream and Programming the FPGA
----------------------------------------------
$ cd <build_dir>
$ PACSign PR -t UPDATE -H openssl_manager -i vortex_afu.gbs -o vortex_afu_unsigned_ssl.gbs
$ fpgasupdate vortex_afu_unsigned_ssl.gbs
FPGA sample test running OpenCL sgemm kernel
--------------------------------------------
Run the following from the Vortex root directory
$ TARGET=fpga ./ci/blackbox.sh --driver=opae --app=sgemm --args="-n128"
