General Description:
After migrating a Foundation project from pre-F1.5 to F1.5 project type, any VHDL-based State Editor modules will have incorrect libraries used in the VHDL code, and will therefore produce errors such as the following when synthesized:
E:#0 Error: D:/14PROJ/WATCH/stopwtch.VHD line 12 No selected element named STD_LOGIC_ARITH is defined for this prefix. (VSS-573) E:#0 Error: D:/14PROJ/WATCH/stopwtch.VHD line 13 No selected element named STD_LOGIC_UNSIGNED is defined for this prefix. (VSS-573) E:#0 Error: D:/14PROJ/WATCH/stopwtch.VHD line -15 Library logical name METAMOR is not mapped to a host directory. (VSS-1071) (FE-dm-hdlc-unknown) E:#0 Error: D:/14PROJ/WATCH/stopwtch.VHD line 16 No selected element named ATTRIBUTES is defined for this prefix. (VSS-573) E:#0 Error: D:/14PROJ/WATCH/stopwtch.VHD line 26 The intermediate file for entity STOPWTCH is not in the library bound to WORK
解决方案
When the project is converted from XACTStepM1 project type to Foundation Series v1.5 project type (See (Xilinx Solution 4363) for details on project conversion), the libraries used by the State Editor are not updated automatically. Therefore, even when a change is made to the State Editor diagram and thus the VHDL code is regenerated by the State Editor, the libraries will be incorrect for use with the Express VHDL compiler. The libraries which are used are compatible with the older XVHDL compiler.
To correct the problem, select Synthesis -> Select Libraries from within the State Editor. Here you may change the libraries which are used. You may simply click on the Default button to change the libraries to be the correct F1.5 libraries, as shown below:
library IEEE; use IEEE.std_logic_1164.all; use IEEE.std_logic_arith.all; use IEEE.std_logic_unsigned.all;
library SYNOPSYS; use SYNOPSYS.attributes.all;
If you have any user libraries, cut them out of the Library Headers window before clicking on the Default button. Paste them back in after clicking on Default.
