Simulate and Generate HDL Code for Tapped Delay Enabled Resettable Synchronous Block

R2026b

This example shows how to simulate a model that uses a Tapped Delay Enabled Resettable Synchronous block and generate HDL code for the DUT subsystem. The block delays a scalar input signal by multiple sample periods and returns the delayed samples as a vector when the external enable signal is true and the external reset signal is false.

Open and Load Model

Load and open the TappedDelayEnableResetModel model. The DUT subsystem contains a Tapped Delay Enabled Resettable Synchronous block. The Number of delays parameter specifies the number of delayed versions of the input signal that the block returns.

load_system("TappedDelayEnableResetModel");
open_system("TappedDelayEnableResetModel/DUT");

Simulate Model

Simulate the TappedDelayEnableResetModel model. The output of the block is a vector. The block returns four-element vector, the first element is delayed by four sample periods, the second element is delayed by three sample periods, and so on.

sim("TappedDelayEnableResetModel");

Generate HDL Code

You can generate the HDL code for a model by using HDL Coder™. Generate the HDL code for DUT subsystem using the makehdl function.

makehdl("TappedDelayEnableResetModel/DUT")
