What Verilog system tasks are supported in the Vivado Simulator (XSim)?


Currently, the 2013.1 Vivado simulator supports all Verilog System Tasks except the following:

1) PLA modeling system tasks:

$async$and$array $async$and$plane
$async$nand$array $async$nand$plane
$async$or$array $async$or$plane
$async$nor$array $async$nor$plane
$sync$and$array $sync$and$plane
$sync$nand$array $sync$nand$plane
$sync$or$array $sync$or$plane
$sync$nor$array $sync$nor$plane

2) Extended VCD generation system tasks:


3) Newly added system tasks and functions in SystemVerilog.

Attmpting to use these system tasks will result in an error message
