SYNOPSYS™15.79 版本发布

The update to version 15.79 incorporates the following changes:

Features:

1.The plastic material model varied by PGM has been improved and is now used more effectively.

2.A problem has emerged related to switch 99, which makes single-configuration optimization utilize multiple cores.While this works as intended and greatly speeds things up, we have found that the Windows operating system often fails to work properly afterward. We are researching this problem and have provided a new command, C99, that controls how many cores are used for this purpose. Fewer used seems to reduce the incidence of this effect. Users are advised to experiment, and let us know if you gain any insight into what may be causing this strange effect.

Bugs Fixed:

1.The number of cases listed as skipped by AEI was sometimes incorrect.

2.GSEARCH did not work properly if switch 99 was turned on.Now it turns that switch off before it runs.

3.The Free-form system build, FFB, when a circular field was specified by CFOV, created the correct set of rays for the merit function, but did not assign the CFOV flag to the system itself.

4.The convolution MTF became inaccurate if the lens pupil was strongly noncircular.

5.If you ran DSEARCH with multiple trial radii values, and the number of authorized cores exceeded the number of cases given by the binary search algorithm, some cases were examined more than once, which could potentially eliminate other good solutions.
