General Description: In the M1.4 release, a new library called "XC4000X" has been added to the Cadence, Mentor, and Viewlogic design entry interface libraries. The "XC4000X" replaces the "XC4000EX" library and supports the following architectures:
XC4000EX, XC4000XL, and XC4000XV
ソリューション
1
The XC4000X library represents a "catch-all" library to be used for designs targeting the XC4000EX, XC4000XL, and XC4000XV architectures.
The supported library macros and primitives for all three architectures are identical. The only difference is support for two additional properties in the XC4000XV architecture.
The collapsing of these three architectures into a single design entry library simplifies the maintenance of these libraries, and reduces redundancy in the interface.
With this new change, targeting to the specific architecture (XC4000EX, XL, or XV) must now be done during the implementation stage via the NGDBUILD, MAP and/or PAR -p options.

To convert a Viewlogic M1.3 schematic design using the XC4000EX library to the XC4000X library, you must run the Altran command. Within an MS-DOS session, navigate to your project directory and run the following command:
altran -l primary xc4000ex=xc4000x
Then update your viewdraw.ini file by modifying the libraries listing in the Project Manager (Workview Office) or the viewdraw.ini file itself (Powerview).
Consult the Viewlogic Interface and Tutorial Guide in the Online Docs for more information about Altran.

To convert a Cadence Concept M1.3 schematic design entered with the XC4000EX library, edit your global.cmd and change the reference to "xce4000ex" to "xce4000x". Also make sure that you either:
- Edit the master.lib library file in $CDS/lib has an entry pointing to the location of the new "xce4000x.lib" library
OR
- Edit your master.local library file in your project directory to point to the location of the new "xce4000x.lib" library.
Open each schematic of your Concept design, type read in the new components by typing: "
get
Then rewrite the schematic by typing:
write
