DC CIRCUIT ANALYSIS
Version 1.1a - May 1993
-----------------------
Corrected a bug in the potentiometer calculation which did not
affect any of the sample problems.
Version 1.2 - June 1993
-----------------------
Added an on-line tutorial which has Hyper-Text like features.
Tutorial is accessed using the F5 key.
Changed the Opening Menu to replace:
Save and Continue
Exit without Saving
Save and Exit
with
Save Circuit As
Save Circuit
Exit
Added F6 command to switch between Analyze Circuit and Modify
Circuit.
Compressed the graphics library file and renamed it from DC.LIB to
DC.IC.
Version 1.3 - March 1994
------------------------
This program requires a 286 or later processor.
The filename is displayed in the Analyze and Modify screens.
The Select Sample Circuit menu will automatically execute Analyze
after selecting a sample circuit.
Modified the calculation to use a double precision matrix of
simultaneous equations resulting in a more accurate calculation.
Convergence criteria is between 1.0e-8 and 1.0e-10 Volts.
Modified P-N junction calculation to use an exponential increase in
current. This eliminates the overshoot of the threshold voltage in
previous versions and results in a more realistic answer. This
change also required the DC.DCL library parameters to be modified.
Replaced Darlington in library with IC containing two transistors.
Previous versions of this program improperly calculated circuits
containing darlingtons.
Added Schottky diodes to library, and replaced conventional diodes
with Schottky diodes where appropriate.
Added Low-Power Schottky sample circuits for AND, NAND, OR, NOR,
and 3-State gates. Also added, Schottky Diode sample circuit.
Corrected overload check to determine if current passing through
the collector-emitter junction of bipolar transistors are
overloaded.
Added 47K output resistors to all ECL ICs in the library.
Modified various sample circuits, including SSSW, SSPOWSW,
SSRPOWSW.
