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 ...
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 ...
To use other RLC package models in an IBIS model: 1. Open the IBIS file in a text editor. 2. Scroll down, and under the [Package] keyword, you will see the various package models available for use. 3. Using the commenting character "|", comment the ...
The low voltage positive emitter couple logic (LVPECL) interface uses two separate single ended buffers, plus on-board resistors to emulate a differential pair. The input output buffer information standard (IBIS) requires that the models be ...
An IBIS Model is a mapping of voltage to current values for a given I/O standard, slew rate, and drive strength. User can estimate the output resistance by using a simple slope formula, in relative to the flow of current. Using Ohm's law: Resistance ...
