线性规划检验作为一种对非线性电路不存在直流解的强有力的计算检验，是众所周知的。这个测试对于寻找非线性电路的所有解是有用的；它也有助于验证在不应该存在工作点的给定区域中不存在直流工作点。然而，由于非专家或初学者编程不容易，LP测试在实际电路仿真中还没有得到广泛的应用。在本文中，我们提出了一种新的LP测试，该测试无需编程即可在SPICE上轻松实现。建议的测试很有用，因为我们可以只使用SPICE轻松地检查解决方案的不存在。
As a powerful computational test for nonexistence of a DC solution of a nonlinear circuit, the LP test is well-known. This test is useful for finding all solutions of nonlinear circuits; it is also useful for verifying the nonexistence of a DC operating point in a given region where operating points should not exist. However, the LP test has not been widely used in practical circuit simulation because the programming is not easy for non-experts or beginners. In this paper, we propose a new LP test that can be easily implemented on SPICE without programming. The proposed test is useful because we can easily check the nonexistence of a solution using SPICE only.
