Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  proposes an efficient analysis flow and an algorithm to identify the worst case noise for por networks with multiple clock domains. First,  apply the Laplace transform on the input current sources to derive the analytical formula. Then,  calculate the circuit frequency response with logarithmic scale frequency components. The frequency domain response is approximated by a rational function using vector fitting modeling. The rational function is used to derive the natural frequency of the por ground networks, and can be converted back into time domain easily. Based on the analysis results,  then present the worst case clock gating pattern algorithm to analyze the por networks with multiple clock domains. The most expensive part of the proposed algorithm is the matrix solving: O(F(N) ldr log f ldr D). Function F is the complexity of iterative solution of complex matrix with dimension N.  assume that there are D clock domains and the frequency spans from 0 to f Hz. Experimental results show that our method is up to 60X faster than HSPICE, and can analyze large circuits which are not affordable by HSPICE.
