Pass-Through and No-Op Implementations
HDL Coder™ provides a pass-through or no-op implementation for some blocks. A pass-through implementation generates a wire in the HDL; a no-op implementation omits code generation for the block or subsystem. These implementations are useful in cases where you need a block for simulation, but do not need the block or subsystem in your generated HDL code.
The pass-through and no-op implementations are summarized in the following table.
Provides a pass-through implementation in which the block's inputs are passed directly to its outputs. HDL Coder supports the following blocks with a pass-through implementation:
This implementation completely removes the block from the generated code. This enables you to use the block in simulation but treat it as a “no-op” in the HDL code. This implementation is used for many blocks (such as Scopes and Assertions) that are significant in simulation but are meaningless in HDL code.
