- This document contains information about running PSpice on a
- Macintosh II.
-
- PSpice, being a circuit analyzer, does not interact with the user. Very
- little about its operation is different than the operation of PSpice on
- any other machine for which we make a PSpice.
-
- To run PSpice:
- Ñ double click on the PSpice application;
- Ñ select open from the File Menu;
- Ñ choose an input (circuit net list) file;
- Ñ choose an output file.
-
- To abort a simulation without quitting PSpice:
- Ñ type a . (period) while holding down the Apple key.
-
- To abort PSpice, either:
- Ñ click on the close box;
- Ñ select Quit from the file menu
-
- Note that once a circuit file has been run (without errors), you may
- double click on its icon to re-run it. This enables you to run long
- analyses overnight. Read under Extended Capabilities for more
- information on this.
-
- If you run PSpice under a shell (the MPW shell, for example), be aware
- that typing:
-
- PSpice eval.cir eval.out
-
- will not behave as typing the same line on an IBM PC would. On the
- Macintosh, all files passed to PSpice are treated as input files,
- whereas on the PC, you may specify the output filename along with the
- input filename. On the Macintosh, both eval.cir AND eval.out will be
- treated as input files.
-
-
-
- Extended Capabilities
-
- PSpice's Macintosh features are limited, due to the nature of the
- application:
- Ñ You may move the window around on the screen
- Ñ You may make the window shrink down to nothing by clicking on the
- Zoom box while holding down the Option key. (The next click on the Zoom
- box restores the window.)
- Ñ You may make the display appear in color by selecting Color
- Monitor in the Color Menu.
- Ñ You may select About PSpice under the Apple Menu to get the
- version number and your ID number.
- Ñ You may define a list of folders in thich to search for Libraries.
- See under Libraries later on.
- Ñ You may (optionally) have PSpice change the Finder information for
- a file if it completes a simulation without errors such that you may
- Shift-Click on a number of files to re-simulate. This is useful if you
- want to make a change to a component value after you have simulated
- once. Select Miscellaneous under the File Menu for more information.
-
- Application Memory Size
- PSpice is set up to run in a 1024K region. This will enable you to
- simulate a circuit of about 10 transistors which is the limit for this
- evaluation version (the production version is limited only by the amount
- of memory available.)
-
-
- Libraries
- We have incorporated an indexing scheme into the library search
- mechanism to speed up access. For each library XXX.LIB, there is a
- corresponding XXX.IND which has information concerning the members of
- the library, such as the offset from the beginning where each .MODEL and
- .SUBCKT may be found. The XXX.IND files are automatically rebuilt
- whenever an inconsistency is encountered.
-
- You may define a sequence of folders in which to search for libraries
- you circuit may need. The Libraries under the File Menu enables you to
- define and delete, as well as to view, the list of folders in which
- libraries are searched. When PSpice encounters a .LIB statement, it
- will first search the folder in which the circuit files is in; second,
- the list of folders you specified, in the order you specified; last,
- PSpice will search the PSpice folder. Select Libraries under the File
- Menu for more information.
-
- The Library search path, along with window placement information is
- saved in a file named PSpicePreference in the root folder on your hard
- disk. The Library information will become invalid if you restore a
- backed-up system from tape. In this case, you must delete the
- PSpicePreference file or your simulations will fail.
