Specified 'noisefmin' is smaller than 1/stop time. 'noisefmin' has been changed to 25 MHz. ************************************************ Transient Analysis `tran': time = (0 s -> 40 ns) ************************************************ Notice from spectre during IC analysis, during transient analysis `tran'. There are 1 IC nodes defined. Notice from spectre during IC analysis, during transient analysis `tran'. Bad pivoting is found during DC analysis. Option dc_pivot_check=yes is recommended for possible improvement of convergence. Initial condition computed for node ring<51> is in error by 885.175 uV (73.7645 m%). Decrease `rforce' to reduce error in computed initial conditions. However, setting rforce too small may result in convergence difficulties or in the matrix becoming singular. DC simulation time: CPU = 8.998 ms, elapsed = 9.68313 ms. Warning from spectre during transient analysis `tran'. WARNING: The cm value is specified for the tran analysis fastcross option but this value is supported only by AMS-Ultra or AMS-Spectre integrated with new Front-End. The simulator uses the fastcross discrete value instead of the cm value. Opening the PSFXL file ../psf/tran.tran.tran ...
