2.4. IP Core Generation Output

The Quartus® Prime software generates the following output file structure for individual IP cores that are not part of a Platform Designer system.
Figure 10. Individual IP Core Generation Output
Table 7.  Output Files of Intel® FPGA IP Generation
File Name Description
<your_ip>.ip Top-level IP variation file that contains the parameterization of an IP core in your project. If the IP variation is part of a Platform Designer system, the parameter editor also generates a .qsys file.
<your_ip>.cmp The VHDL Component Declaration (.cmp) file is a text file that contains local generic and port definitions that you use in VHDL design files.
<your_ip>_generation.rpt IP or Platform Designer generation log file. Displays a summary of the messages during IP generation.
<your_ip>.qgsimc (Platform Designer systems only) Simulation caching file that compares the .qsys and .ip files with the current parameterization of the Platform Designer system and IP core. This comparison determines if Platform Designer can skip regeneration of the HDL.
<your_ip>.qgsynth (Platform Designer systems only) Synthesis caching file that compares the .qsys and .ip files with the current parameterization of the Platform Designer system and IP core. This comparison determines if Platform Designer can skip regeneration of the HDL.
<your_ip>.qip Contains all information to integrate and compile the IP component.
<your_ip>.bsf A symbol representation of the IP variation for use in Block Diagram Files (.bdf).
<your_ip>.spd Input file that ip-make-simscript requires to generate simulation scripts. The .spd file contains a list of files you generate for simulation, along with information about memories that you initialize.
<your_ip>.ppf The Pin Planner File (.ppf) stores the port and node assignments for IP components you create for use with the Pin Planner.
<your_ip>_bb.v Use the Verilog blackbox (_bb.v) file as an empty module declaration for use as a blackbox.
<your_ip>_inst.v or _inst.vhd HDL example instantiation template. Copy and paste the contents of this file into your HDL file to instantiate the IP variation.

<your_ip>.v

<your_ip>.vhd

HDL files that instantiate each submodule or child IP core for synthesis or simulation.
mentor/ Contains a msim_setup.tcl script to set up and run a simulation with a supported Siemens EDA simulator, such as the ModelSim simulator.

/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.

/xcelium Contains an Xcelium* Parallel simulator shell script xcelium_setup.sh and other setup files to set up and run a simulation.
/submodules Contains HDL files for the IP core submodule.
<IP submodule>/ Platform Designer generates /synth and /sim sub-directories for each IP submodule directory that Platform Designer generates.
