Targeting the sysDSP Block by Instantiating Primitives
The sysDSP Block can be targeted by instantiating the sysDSP Block primitives into the design. The advantage of
instantiating primitives is that it provides access to all ports and sets all available parameters. The disadvantage of
this flow is that all this customization requires extra coding by the user. Appendix A details the syntax for the sys-
DSP Block primitives.
