The Quartus® Prime Pro Edition software generates the following IP core output file structure:
Figure 20. IP Generated File Structure
File Name | Description |
---|---|
<your_ip>.ip | The Platform Designer system or top-level IP variation file. <your_ip> is the name that you give your IP variation. |
<your_ip>.cmp | The VHDL Component Declaration (.cmp) file is a text file that contains local generic and port definitions that you can use in VHDL design files. |
<your_ip>.html | A report that contains connection information, a memory map showing the address of each slave with respect to each master to which it is connected, and parameter assignments. |
<your_ip>.qgsimc | Lists simulation parameters to support incremental regeneration. |
<your_ip>.qgscythc | Lists synthesis parameters to support incremental regeneration. |
<your_ip>.qip | Contains all the required information to integrate and compile the IP component in the Quartus® Prime software. |
<your_ip>.sopcinfo | Describes the connections and IP component parameterizations in your Platform Designer system. You can parse its contents to get requirements when you develop software drivers for IP components. Downstream tools, such as the Nios® V tool chain, use this file. The .sopcinfo file and the system.h file generated for the Nios® V tool chain include address map information for each slave relative to each master that accesses the slave. Different masters may have a different address map to access a particular slave component. |
<your_ip>.spd | Required input file for ip-make-simscript to generate simulation scripts for supported simulators. The .spd file contains a list of files generated for simulation, along with information about memories that you can initialize. |
<your_ip>.xml | Contains information about interfaces and parameters of the IP component. |
<your_ip>_bb.v | You can use the Verilog black-box (_bb.v) file as an empty module declaration for use as a black box. |
<your_ip>_generation.rpt | IP or Platform Designer generation log file. It provides a summary of the messages during IP generation. |
<your_ip>_inst.v or _inst.vhd | HDL example instantiation template. You can copy and paste the contents of this file into your HDL file to instantiate the IP variation. |
