Utilizing IPexpress
Designers can utilize IPexpress to easily specify a variety of memories in their designs. These modules will be con-
structed using one or more memory primitives along with general purpose routing and LUTs as required. The avail-
able modules are:
IPexpress Flow
For generating any of these memories, create (or open) a project for the LatticeECP/EC or LatticeXP devices.
From the Project Navigator, select Tools > IPexpress. Alternatively, users can also click on the button in the tool-
bar when the LatticeECP/EC and LatticeXP devices are targeted in the project.
This opens the IPexpress window as shown in Figure 9-4.
