SYNOPSYS: add_sub_ub: Cannot find the architecture "add_sub_ub [xhm]" in the library xblox_4000 (LBR-1) /reanalyzing libraries 


Record #918

Product Family:  Software

Product Line:  Synopsys

Problem Title:
SYNOPSYS:  add_sub_ub: Cannot find the architecture "add_sub_ub [xhm]"
in the library xblox_4000 (LBR-1) /reanalyzing libraries



Problem Description:
Synopsys issues the following error message:
"add_sub_ub: Cannot find the architecture "add_sub_ub [xhm]" in
the library xblox_4000 (LBR-1)"




Solution 1:

 This error message indicates that the path to the XBLOX
DesignWare library is either incompletely or incorrectly
specified, or it is not specified at all.
 The .synopsys_dc.setup file must contain the following
statement:

define_design_lib xblox_4000 -path $DS401/synopsys/    \
		 /libraries/dw/lib/fpga/xc4000

Replace "4000" and "xc4000" with the appropriate family
name when using other device families.
Ensure that the path to the xblox_4000 library is correct
by 'cd-ing' over to the directory.
  An example .synopsys_dc.setup file exists in the following
directory:
$DS401/examples/synopsys/fc4k.synopsys_dc.setup

($DS401 refers to the root location of the XSI/DS401 software.)
