Constraint Overview

Usage: add constraint to any job allocation (srun, sbatch, salloc) in the FPGA partition where you plan to execute a design on the designated FPGA cards.

e.g. srun --partition=fpga --constraint=xilinx_u280_xrt2.12 -A [YOUR_PROJECT_ACCOUNT]

Emulation

Emulation works on all Noctua2 nodes. For the FPGA partition, it’s mandatory to specify a constraint. With the emulation constraint, you state that you don’t rely on any specific FPGA shell or device driver to be active.

--constraint=

--constraint=
`emul`	Emulation only if you use the FPGA partition, but do not use the FPGA cards.
