• 1911 - How can I generate a much smaller IBIS model file that only includes the IO types defined in my project?

  Situation: An IBIS model file from the Lattice web site includes all the programmable IO types a device can be set to, but the IBIS model file is very large and for some simulators, can slow the simulation setup time substantially. It is desired to ...

  There are several ways to do that: 1. The typical usage of the IBIS file is to set up a simulation on an IBIS compatible simulator and have the IO output IBIS model drive a PCB trace with a receiver input attached at the end of the PCB trace, then ...

  The LatticeECP3 LVDS input terminations on die include a midpoint connection to the bank VTT pins on the device. This is why it is recommended in the LatticeECP3 data sheet to leave the bank VTT pins floating when using LVDS input terminations and to ...

  Currently Lattice does not provide LatticeECP3 IBIS model for SERDES input and outputs such as HDINP/N and HDOUTP/N. Alternatively, we recommended you use the LatticeECP3 HSPICE IO Kit to reach their simulation goals. The Lattice HSPICE IO Kit is ...
