IP Core Generation
3. IPexpress shows the current settings for the module or IP in the Source box. Make your new settings in the T ar-
get box.
4. If you want to generate a new set of files in a new location, set the new location in the IPX Target File box. The
base of the file name will be the base of all the new file names. The IPX Target File must end with an .ipx exten-
sion.
5. Click Regenerate. The module’s dialog box opens showing the current option settings.
6. In the dialog box, choose the desired options. To get information about the options, click Help . Also, check the
About tab in IPexpress for links to technical notes and user guides. IP may come with additional information. As
the options change, the schematic diagram of the module changes to show the I/O and the device resources
the module will need.
7. To import the module into your project, if it’s not already there, select Import IPX to Diamond Project (not
available in stand-alone mode).
8. Click Generate .
9. Check the Generate Log tab to check for warnings and error messages.
10.Click Close .
The IPexpress package file (.ipx) supported by Diamond holds references to all of the elements of the generated IP
core required to support simulation, synthesis and implementation. The IP core may be included in a user's design
by importing the .ipx file to the associated Diamond project. To change the option settings of a module or IP that is
already in a design project, double-click the module’s .ipx file in the File List view. This opens IPexpress and the
module’s dialog box showing the current option settings. Then go to step 6 above.
Regenerating an IP Core in ispLEVER
To regenerate an IP core in ispLEVER:
1. In the IPexpress tool, choose Tools > Regenerate IP/Module .
2. In the Select a Parameter File dialog box, choose the Lattice Parameter Configuration (.lpc) file of the IP core
you wish to regenerate, and click Open .
3. The Select Target Core Version, Design Entry, and Device dialog box shows the current settings for the IP core
in the Source Value box. Make your new settings in the Target Value box.
4. If you want to generate a new set of files in a new location, set the location in the LPC Target File box. The base
of the .lpc file name will be the base of all the new file names. The LPC Target File must end with an .lpc exten-
sion.
5. Click Next . The IP core’s dialog box opens showing the current option settings.
6. In the dialog box, choose desired options. To get information about the options, click Help . Also, check the
About tab in the IPexpress tool for links to technical notes and user guides. The IP core might come with addi-
tional information. As the options change, the schematic diagram of the IP core changes to show the I/O and
the device resources the IP core will need.
7. Click Generate .
8. Click the Generate Log tab to check for warnings and error messages.
