Description

Error using xlGenerateForPA (line 35)
Failed to netlist model 'test_opmode.slx' (error code 4). Errors occurred during netlist generation.
'test_opmode/Opmode' has an invalid constant (inf) sample time. Discrete states, continuous states, and tunable parameters are not allowed with constant sample times.

Solution

This is a known issue in Matlab and cannot be resolved within the Vivado Sysgen environment.

To work around the issue:

1) Revert back to Matlab R2013b

2) If feasible use the CONSTANT block instead of the OPMODE block in your model. (See (Xilinx Answer 61951))
