I mean how can a designer choose vhdl93 or... in ,for example, ISE ? Regards, Meysam.

Quartus has limited support for 2008. So you're basically stuck having to use VHDL 1993 for synthesisable code. Modelsim has full 2008 support however, so 2008 in testbenches is fine.

Same issue with SV/Verilog support beyond 2001 (at least they support that).
