*** ERROR "ALG_SINGULAR_JACOBIAN" *** Singular Jacobian matrix.
Some possible causes for a singular Jacobian matrix:
- Model operating outside of its intended region of operation.
- Node/subsystem with no connection to the reference (floating).
- Current loops (voltage sources/inductors in parallel).
- Missing equation and/or missing variable reference.
Potential problem variables/equations:
/uc3842.uc3842_1/d.d1/pi
但是3842没有d这个管脚的啊！这个问题已经困扰了我很多天了，还请各位大虾不吝赐教，谢谢！！
