ToDo

This fork doesn't need a wiki for the project, but a to-do list might be useful

• Collaboration Control

  • Save/Restore viewport to Website with Thumbnail
    • somehow make use of document.getElementById('chipbg').toDataURL() which returns a 3mbyte string. Need clipping!
  • also save 6502 machine state, maybe even trace data
  • also save Highlighting and Annotation

• URL query handling

  • layer visibility control
  • layer loading control, maybe
  • test program running with selected traces - done (short programs, in URL)

• UI improvements

  • add contributed disassembler - done
  • add contributed nodenames - more done, incl datapath controls
  • stop at watchpoint or breakpoint - done
  • load program from URL, for unredistributable ROMs
    • some will need hooks for OS calls
  • implement a putc() so ROMs can write to a window - done
  • implement a getc() so ROMs can read characters from keyboard - done
  • trace named signal sets by name, for pla and datapath inputs - done for datapatch control, fetch and execute
  • add pad layers, or derive them, so metal can be ignored (for memory improvement)
  • overlay text for nodenames, overlay (big) binary digits on busses and storage nodes
  • overlay rectangles for areas of interest
  • patch 6502asm to link back to jssim, launching the program

• simulation speedup ideas

  • see if trace buffer is expensive
    • see if trace buffer could be faster or optional
  • see if logic encoding by short strings is fastest
  • multi transistors
  • multi-source busses - schedule them late
  • pulledup logic outputs - schedule them early

• investigation help

  • count the contention events
