Sequence Feedback block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
HDL Verifier / For Use with DPI-C SystemVerilog

Description

Add-On Required: This feature requires the ASIC Testbench for HDL Verifier add-on.

The Sequence Feedback block promotes a feedback signal from the scoreboard to the sequence in a UVM testbench model. The block implements a Unit Delay (Simulink) block with the Initial condition parameter set to 0.

Ports

Input

Port_1 — Feedback signal from scoreboard subsystem

scalar

The Sequence Feedback block accepts an input signal directly from the scoreboard subsystem.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point

Output

Port_1 — Feedback signal to sequence subsystem

scalar

The Sequence Feedback block outputs a signal directly to the sequence subsystem.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"dpiblklib/Sequence Feedback"

Example: add_block("dpiblklib/Sequence Feedback","myModel/myBlock",MakeNameUnique="on")
