Foundation: Importing Viewlogic designs with multi-page macros
説明
Keywords: Macro, Viewlogic, Foundation, Import
Urgency: Standard
General Description: The Foundation Schematic Editor does not support schematic macros which contain more than one page.
Note that Foundation does support top-level schematics that contain more than one page.
When importing a Viewlogic design which has multi-page macros, the Schematic Editor will merge all macro sheets onto a single page, creating a potentially large schematic.
If the resulting single-page macro is too large, the design can be restructured by introducing an intermediate level of hierarchy, so that all macros are of a reasonable size.
For example, if the original hierarchy of the Viewlogic design was:
TOP.1 --> (MACRO.1, MACRO.2, MACRO.3)
After inserting a level of hierarchy and converting to Foundation, it would look like this:
The restructuring can be done in either Viewlogic (before conversion), or in Foundation (after conversion).
ソリューション
1
Using Viewlogic ---------------
1. Open each sheet (MACRO.1, MACRO.2, and MACRO.3) and then do a Save As MACRO1.1, MACRO2.1, MACRO3.1.
2. Create symbols MACRO1.1, MACRO2.1, and MACRO3.1.
3. Edit the original MACRO.1 schematic to contain just the symbols MACRO1, MACRO2, and MACRO3 with appropriate connections.
4. Delete the original MACRO.2 and MACRO.3 schematics.
(NOTE: This process needs to be repeated for each multi-page macro in the design.)

Using Foundation ----------------
1. Import the Viewlogic design.
2. Open MACRO.SCH. If the page size is acceptable, do nothing.
3. To split the page into 3 macros, use the Cut and Paste commands to create new schematic macros called MACRO1.SCH, MACRO2.SCH, and MACRO3.SCH.
4. Use the Hierarchy -> Create Macro Symbol From Current Sheet command to create symbols MACRO1, MACRO2, and MACRO3.
5. Edit the original MACRO.SCH to contain just the symbols MACRO1, MACRO2, and MACRO3 with appropriate connections. Use File -> Page Setup to reduce the page size.
