You can evaluate any Altera IP core in simulation and compilation in the Quartus II software using the Open Core evaluation feature. Some Altera IP cores, such as Mega core functions require that you purchase a separate license for production use. You can use the Open Core plus feature to evaluate Ip that requires purchase of an additional license until you are satisfied with the functionality and performance. After you purchase a license, visit the Self Service Licensing Center to obtain a license number for any Altera product Figure 2-1: IP Core Installation Path acas quartus-Contains the Quartus ll software ip-Contains the altera IP Library and third-party IP cores [ altera-Contains the Altera IP Library source code H</P core name>-Contains the lP core source files Note: The default IP installation directory on Windows is <drive> alteral< version number; on Linux it is <home directory>/altera/<version number> Related information Altera Licensing Site Altera Software Installation and Licensing Manual 2014 Altera Corporation All rights reserved.

You can use the IP Catalog and parameter editor to select, customize, and generate files representing your custom IP variation The Virtual Processing Image Suite is available only through the Qsys IP Catalog(View >IP Catalog) Double-click any IP core name to launch the parameter editor and generate files representing your IP variation. The parameter editor prompts you to specify your ip variation name, optional ports, architec ture features, and output file generation options. The parameter editor generates a top-level qsys file representing the IP core in your project. Alternatively, you can define an IP variation without an open Quartus II project. When no project is open, select the Device Family directly in IP Catalog to filter IP cores by de Use the following features to help you quickly locate and select an IP core Filter IP Catalog to Show iP for active device family or Show IP for all device familie Search to locate any full or partial IP core name in IP Catalog. Click Search for Partner IP, to access partner IP information on the Altera website. Right-click an IP core name in IP Catalog to display details about supported devices, installation location, and links to documentation Note: The IP Catalog and parameter editor replace the Mega Wizard Plug-In Manager in the Quartus II software. The Quartus II software may generate messages that refer to the Mega Wizard Plug-In Manager. Substitute IP Catalog and parameter editor"for "Mega Wizard Plug-In Manager"in these messages pgrading VIP Designs in 14.0 In Quartus, if you open a design from a 13. 1 or previous version that contains vip components in a Qsys system, Quartus will show a warning message with the title Upgrade IP Components". This message is just letting you know that VIP components within your Qsys system need to be updated to their latest versions, and to do this the Qsys system must be regenerated before the design can be compiled within Quartus. The recommended way of doing this with a VIP system is to close the warning message and open the design in Qsys so that it is easier to spot any errors or potential errors that have arisen because of the design being upgraded Related Information Creating a System With Qsys For more information on how to simulate Qsys designs Using the Parameter Editor The parameter editor helps you lo configure IP core ports, parameters, and oulput file generation options Use preset settings in the parameter editor (where provided)to instantly apply preset parameter values for specific applications View port and parameter descriptions, and links to documentation Generate testbench systems or example designs (where provided) Altera Corporation Customizing Embedded Memory IP Cores □ Send feedbacl UG01068 2014.12.17 Specifying IP Core Parameters and Options 2-3 igure 2-2: IP Parameter Editors IP Pararmeter Editor.unnamed qsys(use/brus 上 tan system cene ate lew 100s n Patameters 3e and parameter unsaved aitclkdrl 0 details ALTCLKCTRL ALTCLKCTRL alticor rsion about thls Cor Author Altera c k butlers tha dive the Global Chek Networ the Regional Cork Tiu ate dacia eu Extera cluCk pah. escriotion no description How do you want to use the ATCKCTFL: For al bal click- Legacy parameter PLLs and Resets Altclkctrl editors arable Crtele end purr lo enable ut hisel- the tluck newu k driven Ly ias bule?

Click Generate HDL, and then confirm the Synthesis and Simulation file options. Verilog is the parameter editor default HDl for synthesis files. If your original IP core was generated for VHDL, select VhDl to retain the original output HDl format 5. To regenerate the new IP variation for the new target device, click Generate. When generation is complete click close 6. Click Finish to complete migration of the IP core. Click OK if you are prompted to overwrite IP core files. The Device Family column displays the migrated device support. The migration process replaces <my_ip> qip with the <my_ip> qsys top-level IP file in your project Note: If migration does not replace <my_ip> qip with <my_ip> qsys, click Project> Add/Remove Files in Project to replace the file in your project 7. Review the latest parameters in the parameter editor or generated HDL for correctness. IP migration may change ports, parameters, or functionality of the IP core. During migration, the Ip core's hDL generates into a library that is different from the original output location of the ip core. Update any assignments that reference outdated locations. If your upgraded ip core is represented by a symbol in a supporting Block Design File schematic, replace the symbol with the newly generated <my_ip>. bsf after migration Note: The migration process may change the IP variation interface, parameters, and functionality This may require you to change your design or to re-parameterize your variant after the Upgrade IP Components dialog box indicates that migration is complete.
