Where can I get board simulation models for REFCLK pins using HCSL or other I/O standards? - Where can I get board simulation models for REFCLK pins using HCSL or other I/O standards? Description Altera® IBIS, IBIS-AMI or HSPICE models do not include REFCLK models for HCSL or other I/O standards for all devices supporting high speed (GX/GT/GZ) transceivers. Resolution You can simulate this interface using HSSI HSPICE or IBIS-AMI models for transceiver RX pin. Board simulation models are located at SPICE Models for Altera Devices .
