Utility Blocks

Utility Blocks — Simulink utility blocks used in models to provide pre-determined functionality.

Introduction

The following blocks are used inside source models to be targeted with HDL Coder. They are designed so that you can add them to your own designs to provide commonly required functional units, and are used in example models.

These blocks can be accessed via the Simulink Library Browser or by entering the following in the MATLAB command window:

Generate one Beat	The Generate one beat block creates data packets to be sent out over Aurora links.
Extract Latency and Sine	The Extract latency sin block is used to disassemble the packet created with the Generate one beat block on the receiving side.
CRC Monitor	The crc tlast difference block output increases if a packet is received with an invalid CRC.
Transmit Frame	This takes an input data and valid signal and generates an axi stream frame-based signal.
Receive Frame	The Receive frame block counts and deconstructs axi stream data packets received over Aurora links.
