FPGA Express: Entity depends on std_logic_1164 which has been analyzed more recently. LBR-28

説明

Keywords: std_logic_1164, recently, LBR-28, Synopsys, synthesis, Express

Urgency: Standard

General Description:
In Foundation Express 2.1.2. If you try and synthesize an HDL file that is
older than the std_logic_1164 library, you will get the following message:

The entity depends on the package std_logic_1164 which has been analyzed more
recently. Please reanalyze this source file and try again. LBR-28.

ソリューション

One solution to this problem is to check your system date/time. If the date on
your PC is earlier than the compile date/time of the IEEE libraries, then you
will not be able to synthesize.

Workaround:
1. Change the system date/time so that it shows the correct date/time.
2. Open the HDL source file(s) with the HDL editor.
3. Re-save the file(s) to update the date/time stamp.
4. Re-analyze the source file(s).
5. Re-synthesize the design.
