Is floating_pkg (VHDL-2006) synthesizable ?

[Ved]

Hi
I have been using the floating package(David Bishop) without any
problem in modelsim for simulation. ( http://www.eda-stds.org/fphdl/ )
But when I put them for synthesis I got compilation errors in
synplicity synplify pro in the float_pkg_c.vhd .
I am pasting the errors below.

Do I need to make any changes in the float_pkg_c for synthesis ?

Please help.

Regards
Ved

The syntax which Synplify Pro is having problems with is this:
-- rtl_synthesis off
-- pragma synthesis_off
......
alias BREAD is READ [LINE, UNRESOLVED_float, BOOLEAN];
alias BREAD is READ [LINE, UNRESOLVED_float];

Two ways to fix.
1) Comment out the "alias" statements (they are not used internally)
2) Switch to version 8.6.2 of Synplify_pro, which supports these aliases.

Hi David ,
I tried both the ways :
Both the ways have problem with DEALLOCATE.
I am pasting error log generated by synplifyPro8.6.2
