SYNOPSYS™15.43 版本发布

The update to version 15.43 incorporates the following changes:

Features:

1. The routine that calculates the intercept of a grazing-incidence ray with an aspheric surface has been improved. Before, it often found the wrong intercept when there was more than one.
2. FIS (fringes at an intermediate surface) has been improved and works better at a decentered surface. It also now lists the Zernike coefficients that model the displayed wavefront.
3. A new surface shape is now available. Surface type USS 27 models a plane grating with a single surface. This is easier to use than the older GRATING specification.
4. The ORDER parameter on a GRATING surface has been reversed, bringing it into agreement with the new USS 27.

Bugs Fixed:

1. If you requested CSTOP and had a decentered CAO on the stop surface, the WAP 2 calculation did not work. Now it deletes any decenter when you use CSTOP.
2. The BTOL entry RANGE XDC range did not work.
3. The default RANGE for PFTEST surfaces in BTOL was sometimes too large, causing ray failures in the tolerance calculation.
4. Some kinds of ray failures during a BTOL run would loop indefinitely. Now it aborts and tells you which parameter was at fault.
