Synopsys FPGA/Design Compiler: Error: The entity 'add_sub_ub' depends onthe package 'std_logic_arith' which has been analyzed more recently.


Record #2657

Product Family:  Software

Product Line:  Synopsys

Problem Title:
Synopsys FPGA/Design Compiler: Error: The entity 'add_sub_ub' depends
onthe package 'std_logic_arith' which has been analyzed more recently.



Problem Description:
Keywords: add_sub_ub, std_logic_arith, LBR-28, OPT-100, compile, Synopsys, desig
n compiler, FPGA compiler

Urgency: Standard

Problem Description:
During compile of a VHDL or Verilog design for Synopsys, get following error.
Error: The entity 'add_sub_ub' depends on the package 'std_logic_arith'
	which has been analyzed more recently.
	Please re-analyze the source file for 'add_sub_ub' and try again. (LBR-2
8)
Information: Compile terminated abnormally. (OPT-100)



Solution 1:

Resolution 1:
The usually means the DesignWare and Simulation Libraries are older than current
 version of Synopsys, they need to be re-compiled.  Please refer to Solution rec
ord 1189 more additional information on how to re-compile DesignWare and Simulat
ion libraries.



Solution 2:

Another possible cause of this problem is that the define_design_lib
and synthetic_library variables in the .synopsys_dc.setup
file are not consistent.  For example, if the define_design_lib
and synthetic_library are set:


define_design_lib xdw_4000ex -path /path1/path2/xc4000ex
synthetic_library = {xdw_4000e.sldb standard.sldb}


or


define_design_lib xdw_4000ex -path /path1/path2/xc4000e
synthetic_library = {xdw_4000ex.sldb standard.sldb}


In the first case, the define_design_lib is pointing at XC4000ex
XDW, but the synthetic_library is pointing to the XC4000E .sldb file.
In the second case, the synthetic_library is okay, but the
define_design_lib is pointing to the XC4000E XDW files, instead of the
XC4000EX.  Make sure your variables are consistent.  Either use
the example .synopsys_dc.setup files in $XILNX/synopsys/examples, or
make sure XC4000E path and files are used together, and
make sure XC4000EX path and files are used together.
