SYNOPSYS™15.97 版本发布

The update to version 15.97 incorporates the following changes:

Features:

1. SSU and RSU will now accept a number and only operate on that configuration it is entered.

2. A new tolerance desensitization operand is available. SDU will evaluate the sum of the squares of the change in paraxial angle UA at each surface. If this is large, then even if it is compensated elsewhere, the surfaces will have tight tolerances.

3. Operands have also been defined for RUD (the difference between the incidence angle of the full-field upper and lower rim rays), which is squared and may help reduce contributions to off-axis aberrations, and DAA, the difference in SA3 contributions at adjacent surfaces. If this is large, then tolerances may also be tight on those surfaces,

4. A new command, RUDIFF, calculates the difference in angle between the upper and lower rim rays, compared to the surface normal, in radians, and prints the sum-squared value.

5. 优化选项QPLUS现在添加在XC 1 1 0处的附加光线。当子午光线将追迹，但弧矢光线将不追迹时，这将避免失败。

Bugs Fixed:

1. The command LLB, which loads the last 20 commands into an editor, did not work properly.

2. The ZSPACE option in ZSEARCH did not work as it should. It now works better after applying a much higher damping.

3. If you changed ACONs and varied the GLM in the new one, the program tested for a glass model in ACON 1.

4. The PAD scan feature does not work with a zoom lens that has been refocused via the ZFOCUS command.
