What should I do if check-in tests failed when first installing OpenFPGA?

First, check to make sure all dependencies for OpenFPGA and Python have been installed and are up-to-date on the desired device. To see the full list of depenencies, please visit our github dependencies page. This issue has been discussed in issue 280.

How to sweep design parameters in a task run of OpenFPGA design flow?

Testing multiple script parameters for a variable is possible by modifying the task.conf file. Doing so will create a job for each combination of the variables. A solution is discussed in issue 228.

How do I setup OpenFPGA to be used by multiple users on a single device?

OpenFPGA can support multiple users on a shared device using the environment variable OPENFPGA_ROOT. The OpenFPGA script for running tasks needs OPENFPGA_ROOT to be the path to the OpenFPGA root directory. Users can then run the script on a task in the current working directory. A solution is discussed in issue 209.
