The Xilinx ® LogiCORE ™ IP FIR Compiler v7.2 core bit accurate C model is a self-contained, linkable, shared library that models the functionality of this core with finite precision arithmetic. This model provides a bit accurate representation of the various modes of the core, and it is suitable for inclusion in a larger framework for system-level simulation or core-specific verification.
This chapter provides information about the bit accurate C model for 32-bit and 64-bit Linux, and 32-bit and 64-bit Windows platforms.
The model consists of a set of C functions that reside in a shared library. Example C code is provided to demonstrate how these functions form the interface to the C model. Full details of this interface are given in C Model Interface .
The model is bit accurate but not cycle-accurate; it performs exactly the same operations as the core. However, it does not model the core latency or its interface signals.
The C model ZIP files are delivered in the cmodel directory of a generated core.
