This paper proposes a methodology to simulate temperature
dependent timing in standard cell designs. Temperature
dependent timing characteristics are derived from standard delay
format (SDF) files that are created by synthesis tools automatically. A case study
is also presented in this paper where the temperature dependent frequency variation
of a ring oscillator is simulated demonstrating the necessity of temperature dependent
timing simulations. An adaptively refineable partitioning method for simulating standard
cell designs logi-thermally is proposed as well. This paper also introduces recent
enhancements in the CellTherm logi-thermal simulator developed in the Department of
Electron Devices, BME, Hungary.
