Lattice Semiconductor
IP Core Generation and Evaluation
Hardware Evaluation
The TSMAC IP core supports Lattice’s IP hardware evaluation capability, which makes it possible to create ver-
sions of the IP core that operate in hardware for a limited period of time (approximately four hours) without requiring
the purchase of an IP license. It may also be used to evaluate the core in hardware in user-defined designs.
Enabling Hardware Evaluation in Diamond:
Choose Project > Active Strategy > Translate Design Settings . The hardware evaluation capability may be
enabled/disabled in the Strategy dialog box. It is enabled by default.
Enabling Hardware Evaluation in ispLEVER:
In the Processes for Current Source pane, right-click the Build Database process and choose Properties from the
dropdown menu. The hardware evaluation capability may be enabled/disabled in the Properties dialog box. It is
enabled by default.
Updating/Regenerating the IP Core
By regenerating an IP core with the IPexpress tool, you can modify any of its settings including: device type, design
entry method, and any of the options specific to the IP core. Regenerating can be done to modify an existing IP
core or to create a new but similar one.
Regenerating an IP Core in Diamond
To regenerate an IP core in Diamond:
1. In IPexpress, click the Regenerate button.
2. In the Regenerate view of IPexpress, choose the IPX source file of the module or IP you wish to regenerate.
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.
