PLL Usage in IPexpress
Including sysCLOCK PLLs in a Design
The sysCLOCK PLL capability can be accessed through the IPexpress GUI. The following section describes the
usage of IPexpress.
IPexpress Usage
The LatticeECP/EC and LatticeXP PLL is fully supported in IPexpress in the ispLEVER software. IPexpress allows
the user to define the desired PLL using a simple, easy-to-use GUI. Following definition, a VHDL or Verilog module
that instantiates the desired PLL is created. This module can be included directly in the user’s design.
Figure 11-6 shows the main window when PLL is selected. The only entry required in this window is the module
name. After entering the module name, clicking on “Customize” will open the “Configuration” window as shown in
Figure 11-7.
