Verilog Code for Fixed Delay Mode
Variable Delay Mode
The following code shows how to instantiate the IDELAY module in variable delay mode.
IDELAYCTRL must also be instantiated when operating in this mode (see
Overview,” page
VHDL Code for Variable Delay Mode
// The IDELAYCTRL primitive must be instantiated in conjunction with
// IDELAY
// primitive when used in Fixed Delay Mode.
// Module: IDELAY
// Description: Verilog instantiation template
// Fixed Delay Mode
//
// Device: Virtex-4 Family
//-------------------------------------------------------------------
// Instantiation Section
//
IDELAY U1
//Set IOBDELAY_TYPE attribute to FIXED for Fixed Delay Mode
//synthesis attribute IOBDELAY_TYPE of U1 is "FIXED";
//Set IOBDELAY_VALUE attribute to 31 for center of delay element
//synthesis attribute IOBDELAY_VALUE of U1 is 31;
