Examples
//IO_TYPE, PULLMODE, SLEWRATE and DRIVE assignment
output portB /*synthesis IO_TYPE="LVCMOS33" PULLMODE =”UP” SLEWRATE =”FAST”
DRIVE =”20”*/;
output portC /*synthesis IO_TYPE="LVDS25" */;
//OPENDRAIN
output portA /*synthesis OPENDRAIN =”ON”*/;
//PCICLAMP
output portA /*synthesis IO_TYPE="PCI33" PULLMODE =”PCICLAMP”*/;
// Fixeddelay
input load /* synthesis FIXEDDELAY="TRUE" */;
// Place the flip-flops near the load input
input load /* synthesis din=”” */;
// Place the flip-flops near the outload output
output outload /* synthesis dout=”” */;
