System Objects

Predefined and user-defined System object™ support for HDL code generation

Functions

`hdl.RAM`	Single, simple dual, dual, true dual, or simple tri-port RAM for memory read/write access
`hdl.BlackBox`	Black box for including custom HDL code
`hdl.Delay`	Delay input signal by number of samples (Since R2021a)
`hdl.TappedDelay`	Delay input signal and output all delayed versions (Since R2021a)
