Xilinx Blocks

It is instructive to note that the following model produces behavior identical to the one with the Sync block. This one, though, requires the designer to examine the two upstream pipelined sources and to insert the correct delay line length to balance the two pipelines. Moreover, should a pipeline stage be either added to or removed from the sine wave generator, the pipeline balancing delay line would have to be re-tuned. The Xilinx Sync block allows such balancing operations to be automated.

The Sync block can be configured to have up to four channels and to add latency to all channels beyond the minimum required.

Block Parameters Dialog Box

The block parameters dialog box can be invoked by double-clicking on the block icon in your Simulink model. The dialog box is illustrated below.

Parameters specific to the block are:

Number of channels: Specifies the number of channels to process, hence the number of input and output ports. The number of channels can be 2, 3, or 4.

Latency (minimum per channel): Specifies the smallest amount of delay that will be added to any channel. Latency will also be the amount of latency
