Known Limitations with Design

The limits for all outputs in FDD v3.0.0 uses same Min and Max values which will cause PIL test coverage issue due to limit function.

UNIT TEST CONSIDERATION

The limits for all outputs in FDD v3.0.0 uses same Min and Max values which will cause PIL test coverage issue due to limit function.
