Abstract :
In this paper, a Frequency domain Fast Wavelet Collocation Method (FFWCM) is proposed for the simulation of high-speed linear VLSI circuits. Compared with the time domain Fast Wavelet Collocation Method, the proposed FFWCM solves the state equation in the frequency domain and reduces the problem unknowns by avoiding expanding all the state variables with wavelet functions. Moreover, frequency domain singularities can be easily handled by an efficient adaptive scheme and the simulation error bound is guaranteed in the frequency domain. As a result, memory space and simulation time are greatly reduced by FFWCM, which makes it efficient for simulating large scale circuits. Numerical experimental results have further demonstrated the promising features of FFWCM
