Still Electronic Workbench (EWB 5.12) may be using an old LG TV’s horizontal scanning times and TL494 SMPS control of integrated electronic workbench’s simulation files.
The lucky ones who already had to deal with a program on their own experience , it either makes all too perfect or stops the simulation and produces an error , and error in the commentary to write what horrible and nothing in the case. Bring me the points identified ways of taming . Perhaps for professionals they were clear from the outset , but for beginners they prove significant.
Example of a program EWB 5.12
1. Program does not like schemes where slew rate is infinitely large . In this case put in parallel with the signal one pF capacitor , or a little more . On the operation of the scheme will not be affected , and the process goes well .
2 . Bipolar transistors do not pull the load – voltage change Earley (Early voltage).
3 . At FETs in a similar case , the gain change (transconductance coefficient).
For an example, the circuit with the power supply is not quite an exact analogue of TL 494. To change the frequency , you need to open a chip .
