Using files

Opening and closing files in PSpice is similar to using files in other Windows programs.

If you open a section that is currently being created by the simulation, added traces are automatically updated.

Double-click the symbol next to a trace name in the plot window legend to view information about the trace, including which file its data originated from.

To open a file

1. On the toolbar, click the Open File button.
2. Select the name of the file from the list. To use a file from a different directory or drive, select it from the list.
3. Click OK.
4. If the file has multiple sections with different analysis types, the Analysis Type dialog box appears.
   • Click the appropriate Analysis type. Select from AC sweep, DC sweep, or Transient.
5. If the file has multiple sections of data of the selected analysis type, the Available Sections dialog box appears. Do one of the following:
   • Click the appropriate sections.
   • To use all the listed sections, click All.
6. Click OK.
7. If any simulation-generated errors are found, a message appears. Click OK to view the error messages, or click Cancel to ignore the errors.

To close a file

1. From the File menu, select Close.
   All data files used by the currently selected plot window are closed. Any other plot windows that use these files are also closed.

Invalid node names

Certain characters are not valid for use in net names or node names because they are either reserved for special use or are not recognized, by PSpice. A list of invalid characters, which should not be used when naming wires, is given below.

@	'at' symbol
%	percent sign
&	ampersand
*	asterisk
+	plus sign (only as initial character)
<space>	Space
?	Question mark
~	Tilde
#	Hash
^	Power of
	"Double quotes
\\	Back slashes
!	Exclamation mark
(	Opening braces
)	Closing braces
	'Single quotes
<	Lesser than
>	Greater than
=	Equals
[	Opening square braces
]	Closing square braces

Besides the characters listed above, you should not use the reserved word CN,- for naming parts or nets. CN is a reserved word used for canonical names.

Limits in PSpice and Probe

The following limits apply to PSpice and Probe:

Feature	Maximum limit
analog display in Probe	400 traces, or 2 times the number of sections, whichever is greater
digital display in Probe	400 traces, or 2 times the number of sections, whichever is greater
number of analog nodes that can be stored in a.DAT file	2**31 (~2,147K)
number of digital nodes that can be stored in a.DAT file	2**15 (~32K)
Monte Carlo analysis	10,000 runs
