Unless otherwise indicated, the layout editor only supports uppercase characters. If you enter lowercase characters, the tool converts them to uppercase. Printable characters are generally any key on a standard keyboard with the exception of Tab, Backspace, Enter, function keys, Esc, and navigation keys (Arrows, Home, and so on.). 7 s" u) u" _$ W) Z8 Y

Although refdes names support the period (.), avoid using it as the period is used as a delimiter when referring to a pin: for example, <refdes>.<pin number>.

2 File names adhere to operating systems restrictions except if they are stored in the database, where they assume the least common denominator. For example, a .psm file becomes a package symbol in the database so its least common denominator is the package name restriction. Spaces in the name are not supported. It is strongly suggested that you use lower case, especially for those names stored in the tool database. ; I( [8 n7 Q* o

4 The default maximum number of characters is 31. You can set the initial length for new designs to a maximum length of 255 by using the allegro_long_name_size environment variable (choose Setup - User Preferences (enved command)). You can change the size in existing designs by choosing Setup - Design Parameters (prmed command) and specifying a new maximum for the Long Name Size parameter in the Design tab.

Note: For releases prior to 16.0, the environment variable allegro_long_package_name is only used as part of the uprev process to override the design's default name length limit. |
