in need of ieee_proposed library

Hiii..

i urgently need the latest version of ieee_proposed library
i downloaded it from **broken link removed** but last update is 2010..

any help to get the latest version please

thanks alot..

that is the latest version.
Actually, the latest version is is part of the VHDL 2008 standard, so wont change until the next version of VHDL

Why do you think theres a newer version?

i thought of the existence of a newer version as whenever i synthesis any module using ieee_proposed i got these warnings

WARNING:HDLCompiler:746 - "E:\Masters\VHDL_Code\libs\ieee_proposed pkg\fixed_pkg_c.vhdl" Line 1470: Range is empty (null range)
WARNING:HDLCompiler:746 - "E:\Masters\VHDL_Code\libs\ieee_proposed pkg\fixed_pkg_c.vhdl" Line 1471: Range is empty (null range)
WARNING:HDLCompiler:746 - "E:\Masters\VHDL_Code\libs\ieee_proposed pkg\fixed_pkg_c.vhdl" Line 1472: Range is empty (null range)


and this is as long as i'm working with Virtex-6
using any other family like Virtex-5 beside the previous warnings, i got alot of error messages

searching here and there i found someone that is talking about "Fixed_pkg_c.vhdl version is 1.3 of 2011" while mine is 1.1 of 2010

so any idea how can i overcome these warnings

thanks

The warnings are expected - those arrays have a deliberate null range.

The errors probably come from the fact that the Xilinx synthesisor is really really bad at VHDL. Did you download the Xilinx compatible version of the IEEE proposed library?
And the clue is in the name - IEEE_proposed is not a real library and is not an official release. It was a '93 compatible verison of the floatfixlib that was included in VHDL 2008. Vendors have been very very slow in including the proper version, so people are stuck using the IEEE proposed library and hoping that it works. I suggest raising an enhancement request with Xilinx.
