WebDepartment of Electrical & Computer Engineering I believe that Spectre treats the iprobe like a voltage source with 0 V. In Modified Nodal Analysis, currents through voltage sources appear as unknowns and are explicitly solved for (unlike most other currents), which might give more precise results for these currents.

WebMar 18, 2024 · On bigger code, it's not so obvious, in particular if you partially break the loops (i.e. breaking L3 and L2, but not L1). Since it will jump to label position, unconditionally, a bit of code inserted where it should not be inserted and you're dead. That's why it's less maintainable to use a goto.
