New File Format Ideas

Symbol

• Improved ERC capabilities

  • every pin allows multiple modes, which can be selected in schematic
  • additional constraints: (analog, digital, digital/SDA,... ), voltage range, electrical net (galvanic separator has two electric independent netgroups)

• multiple subsymbols which are graphically independent

• allow embedding of spice symbols

• embedding of datasheet?

• net ties

• more flexible power Symbol specification

• every element can have arbitrary key-value Pairs

• allow specialization to support atomic parts

• visual alternatives (IEC, ISO, small/big,...)

  

• pin/gate swapping

  • allow logical specification if pin type is allowed there (including optional register allocation check)

• better link between symbol and footprint (pin name instead of number sometimes?)

• pin can hold multiple numbers (proper alternative for pin-stacking)

Schematic

• Multichannel hierarchical sheets (AD: Multi-Sheet and Multi-Channel Design)
• Allow grouping of parts/nets (AD: Defining Net Classes by Area on a Schematic)
• Subschematic templates which can be imported (LP: Support Design Blocks and prebuild Subschematics, AD: Design Reuse)
• Multiple hierarchical entities which are connected via a bus (like in Altium)
• allow specifying default symbol design for hierarchical sheet
• specifying PCB constraints (diff-pair, cap near IC,...)
• interactive simulation graphs like in qucs
• variants support
• improved bus <-> net style
