irun/ncsim/ncvlog SystemVerilog support options

SimhanAnalog

I see the following options for SystemVerilog in irun/ncsim/ncvlog. Why are there two options for SV 2005 and 2009.

What option to use for the latest SystemVerilog 2012(IEEE 1800-2012 SystemVerilog) standard?

-SV -- Enable SystemVerilog features
-SYSV05 -- Enable SystemVerilog features with only SV-2005 and earlier keywords
-SYSV09 -- Enable SystemVerilog features with only SV-2009 and earlier keywords
-SYSV2005 -- Enable SystemVerilog features with only SV-2005 and earlier keywords
-SYSV2009 -- Enable SystemVerilog features with only SV-2009 and earlier keywords

  • -sem2009 is a temporary switch in 14.20 that enables the 2009-onwards scheduling semantics, it has nothing to do with the language parsing itself.
    Without this switch the scheduling follows the 2005 semantics in Incisive 15.10 and older. This becomes the default from version 15.20.
    For more information, open the documentation tool:
    linux> cdnshelp -search "-sem2009"
