Designing a composite amplifier with the OPA1655 I need to simulate the stability, the simulation comes with the following error:
"Floating point overflow (0xc0000091)
Status Bar Text: Preparing the DC analysis matrix.
Stack: LoadDevices
Part: X1.R_R129 "
the used code is:
"X_H1 N45999 OUT N161737 MID BLOCK_DC_H1_OPA1655
.SUBCKT BLOCK_DC_H1_OPA1655 1 2 3 4
H_H1 3 4 VH_H1 1K
VH_H1 1 2 0V
.ENDS BLOCK_DC_H1_OPA1655"
The circuit does it ok with another opamp, so I am certain it is in the .LIB file.
When I replace the SUBCTK function into R_H1 3 4 1K, a resistor, the floating point overflow is gone, but the stack keeps loading continuously.
Hope that one has met the same problem and found the solution.
I would be very happy!
