sfx_compress_waveform

Spectre FX provides options to control waveform compression to generate a reasonably sized waveform file for a large number of signals to be saved. The high-level option sfx_compress_waveform controls the tolerance of voltage and current, as shown below.

sfx_compress_waveform	0	1	2 (Default)	3
sfx_compress_waveform_vabstol		3e-4	1e-3	5e-3
sfx_compress_waveform_vreltol		0	0	0
sfx_compress_waveform_iabstol		1e-12	1e-12	1e-12
sfx_compress_waveform_ireltol		0.005	0.01	0.02
	Disable compression for debugging purpose	Accurate compression	Meet the general usage	A little more aggressive setting to reduce the size further

sfx_compress_waveform_vabstol

Specifies the absolute voltage error tolerance for waveform compression.

sfx_compress_waveform_vreltol

Specifies the relative voltage error tolerance for waveform compression.

sfx_compress_waveform_iabstol

Specifies the absolute current error tolerance for waveform compression.

sfx_compress_waveform_ireltol

Specifies the relative current error tolerance for waveform compression.
