GOST styled IC symbols have some errors #42

GOST styled IC symbols generated by QEDA are not 100% compliant to ESKD.
The main complaint here are main body dimension and lack of IC descriptor.

  1. Main body dimensions.
    The main body is the middle empty part of IC symbol body. It should be at least 10 mm wide. QEDA generates it too small (5 mm or less).
  2. IC descriptor
    Every IC symbol should have IC descriptor inside it's main body. It's either a specific symbol or letter code.
  3. IC name.
    This one is optional.
    IC name should be placed inside main body under IC descriptor. But it is often placed under the main body.

  1. Unfortunately these IC descriptors are GOST specific therefore they are not included to component descriptions. Current IC descriptors are exctracted from keywords. See for details (purposes variable):

https://github.com/qeda/qeda/blob/master/src/symbol/gost/ic.coffee

So, possible solution is to add new entries to this array, could you please advice correspondent ones.

Alternative option is to add component specific settings feature, this work is planned to some future.

  1. Long string with a few of pins looks quite ugly. Another limitation for multi-part symbols in KiCad is that we can have only one attribute position for all parts. It is inconvenient, therefore attribute is placed above the element for multi-part symbol. I guess some setting may be added in order to choose this attribute position.
