Figure 9-5. Generating Pseudo Dual Port RAM (RAM_DP) Using IPexpress in Diamond
In this right pane, options like the Device Family, Macro Type, Category, and Module_Name are device and
selected module dependent. These cannot be changed in IPexpress.
Users can change the directory where the generated module files will be placed by clicking the Browse button in
the Project Path.
The Module Name text box allows users to specify an entity name for the module they are about to generate.
Users must provide this entity name.
Design entry, Verilog or VHDL, by default, is the same as the project type. If the project is a VHDL project, the
selected design entry option will be “Schematic/ VHDL”, and “Schematic/ Verilog-HDL” if the project type is Verilog-
HDL.
The Device pull-down menu allows users to select different devices within the same family, MachXO in this exam-
ple.
Then click the Customize button.
This opens another window where users can customize the RAM (Figure 9-6 and Figure 9-7).
