Dear Electric buglist,
I'm having a problem with MOSFETs when using the "Analog" technology option
(actually it seems to be the choice of SCMOS rules rather than Submicron rules
in the ProjectSettings->Technology menu). Electric thinks the width of some
transistors is 2 lambda bigger than it really is.
If I instantiate the P-Transistor-Scalable or N-Transistor-Scalable I get a
MOSFET with a width of 3 lambda and the active region under the poly is
correctly drawn at 3 lambda. However, if I use the plain P-Transistor and
N-Transistor components and check the properties of the transistors the width
will be reported as 5 lambda, even though the transistors are drawn with an
actual width of 3 lambda. The offending transistors are also drawn with a 3
lambda extension of the gate rather than 2 lambda.
Moving the cursor over these transistors shows that Electric thinks the pin in
the channel is extended 1 lambda beyond the active at each end, only for the
plain transistors.
Deselecting the "ProjectSettings->Technology->Analog" option and changing from
"SCMOS rules" to "Submicron rules" appears to fix the problem.
I'm using Electric 8.07 on Red Hat Enterprise 4 linux with java version
1.6.0_07. Am I doing something wrong here, or overlooking something?
Thanks,
Joe
