Just for completeness, Mentor's Precision also supports the P1735 standard as
does Modelsim. You are right that there is no full support (Precision supports
an early draft version) but I don't believe we have to be concerned about P1735
since there is already a lot of pressure to get full support for it.

The current problem (correct me if I am wrong) is not the simulator/synthesis
tools but P&R since the netlist out of synthesis into P&R is still unencrypted
which defeats the point somewhat.

Hans.
