SYNOPSYS™15.50 版本发布

The update to version 15.49 incorporates the following changes:

Features:

1. SOLID and DSOLID now accept the mnemonic SPART, which sets the partition number for rendering surfaces. The default partition is very fine -- making a beautiful smooth curve -- but the DXF file from DSOLID was huge. Now you can request a coarser partition, and the file will be smaller.

2. We have enhanced the algorithm that finds the real pupil. It can still fail, in cases where the chief ray is close to a caustic, but it is more robust now.

3. The SINGLE input for ZSEARCH now accepts an integer number, as does DSEARCH.

4. We have updated the Ohara glass catalog, adding some new glass types.

5. Also, we have implemented a new feature: sn MOLD rate will alter the index of most of the low Tg glasses according to the rate at which pressed lenses are cooled. The index depends on this rate, and is somewhat lower than the catalog value. The data from Ohara are fully implemented, while Schott provides only a single molded value, from which one cannot extract the effect of the cooling rate. In any case, the change in index is modeled as MELT data, which apply to a specified surface and become part of the RLE file.

Bugs Fixed:

1. The previous version did not provide a way to turn off a selection in the WorkSheet.
