Hardware Evaluation
The Dynamic Block Reed-Solomon Encoder IP core supports Lattice’s IP hardware evaluation capability, which
makes it possible to create versions of the IP core that operate in hardware for a limited period of time (approxi-
mately four hours) without requiring the purchase of an IP license. It may also be used to evaluate the core in hard-
ware 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.
