2.3. Generated File Structure

The Intel® Quartus® Prime Pro Edition software generates the following IP core output file structure.
Figure 4.  eCPRI IP Core Generated Files
For more information about the file structure of the design example, refer to the eCPRI Intel FPGA Design Example User Guide.

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>_generation.rpt IP or Platform Designer generation log file. A summary of the messages during IP generation.
<your_ip>.qgsimc Lists simulation parameters to support incremental regeneration.
<your_ip>.qgsynthc Lists synthesis parameters to support incremental regeneration.
<your_ip>.qip

Contains all the required information about the IP component to integrate and compile the IP component in the Intel® 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® II tool chain use this file. The .sopcinfo file and the system.h file generated for the Nios® II 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>.csv Contains information about the upgrade status of the IP component.
<your_ip>.bsf A Block Symbol File (.bsf) representation of the IP variation for use in Intel Quartus Prime Block Diagram Files (.bdf).
<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>.ppf The Pin Planner File (.ppf) stores the port and node assignments for IP components created for use with the Pin Planner
<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>_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.
<your_ip>.v or <your_ip>.vhd HDL files that instantiate each submodule or child IP core for synthesis or simulation.
mentor/

Contains a ModelSim* script msim_setup.tcl to set up and run a simulation.

synopsys/vcs/

synopsys/vcsmx/

Contains a shell script vcs_setup.sh to set up and run a VCS* simulation.

Contains a shell script vcsmx_setup.sh and synopsys_ sim.setup file to set up and run a VCS* MX simulation.

aldec/

Contains a shell script rivierapro_setup.sh to setup and run a Riviera-PRO* simulation.

xcelium/

Contains a shell script xcelium_setup.sh and other setup files to set up and run an Xcelium* simulation.

submodules/ Contains HDL files for the IP core submodules.
<child IP cores>/ For each generated child IP core directory, Platform Designer generates synth/ andsim/ sub-directories.
