IP Core Register Read 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:
SoC Blockset for AMD / SoC System Simulation / Memory
HDL Coder / SoC System Simulation / Memory

Description

The IP Core Register Read block models a write operation from a processor to hardware logic. The block receives data sent with a Register Write block from the processor. You can define the register offset in the Hardware Mapping tool.

Ports

Output

data — Data output

vector

This port outputs the data vector received from the processor, starting at the offset address from the base address of the IP core. Set the offset address in the Hardware Mapping tool.

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

Parameters

Register name — Name of register

RegA (default) | character vector

Match this name to the Register name parameter specified in the Register Write block.

Example: AddressReg1

Output data type — Data type of output data

uint16 (default) | single | int8 | uint8 | int16 | int32 | uint32 | boolean | fixed point data type

Select the data type for the output data. This value must match the value selected for the Register Write block.

Output vector size — Vector size of output data

1 (default) | positive integer

Specify the vector size of the output data as a positive integer. This value must match the value selected for the Register Write block.

Sample time — Simulation interval of sampling

-1 (default) | nonnegative scalar

Specify a discrete time interval, in seconds, at which the block outputs data. If this value is -1 (default), the sample time is inherited from the model.

Programmatic Use: Add Block

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

"socmemlib/IP Core Register Read"

Example: add_block("socmemlib/IP Core Register Read","myModel/myBlock",MakeNameUnique="on")
