Design Made Simple with PAC-Designer Software
Lattice's PAC-Designer® software, a PC-based software tool, and Frequency Synthesizer enable easy configuration of provides simple and intuitive pull-down menus for config- various counters and other options. Configurations can be uring all programmable features of the device. In addition, downloaded into ispClock devices from a PC parallel port.
design utilities like the Skew Editor, Frequency Calculator

1. Specify I/O interface type.
3. Graphically adjust skew for each clock output.
2. Synthesize M, N & V counters from output frequencies.
