|
this files describe the roadmap, I think should be for the OpenAccess Driver/Parser
|
||||||
|
|
||||||
|
- EVERYONE WHO WANT TO CONTINUE THIS WORK SHOULD READ AT LEAST MY REPPORT,
|
||||||
|
concept like EMH are really welcome ...
|
||||||
|
|
||||||
|
ON THE DRIVER
|
||||||
|
|
||||||
|
- first write the driver as mixed for debug purpose : convert AMS device using freePDK45
|
||||||
|
xml techno file from hurricane, but use existing OpenAccess files for
|
||||||
|
freepdk45 techno, separating technology converting with device
|
||||||
|
converting (working on it)
|
||||||
|
|
||||||
|
- then check that, layout is working correctly, all components,
|
||||||
|
metals, poly ... are present and DRC works without errors.
|
||||||
|
|
||||||
|
- then concentrate on how to really get the LSW have the layers (colors), and
|
||||||
|
encounter eating converted techno without errors, and add the techno
|
||||||
|
convertion ... don't join the techno convertion with device, the
|
||||||
|
main reason is design kits : a design kits basicly contain libs for
|
||||||
|
techno and libs for cells.
|
||||||
|
|
||||||
|
- test with a "small" cpu, like a mips, and some ampli, miller ...
|
||||||
|
|
||||||
|
- when and ONLY when the layer is correctly converted totaly,
|
||||||
|
populate symbolic view, to show a rectangle with input on left, and output
|
||||||
|
on right.
|
||||||
|
|
||||||
|
- then populate schematic view, to show shematic "device" will be placed
|
||||||
|
like in layout.
|
||||||
|
|
||||||
|
ON THE PARSER
|
||||||
|
|
||||||
|
- first use a mixed mode like for the driver
|
||||||
|
|
||||||
|
- convert only analogic because we have no numerical hurricane
|
||||||
|
freePDK45 cells.
|
||||||
|
|
||||||
|
- see in a pharos, CellViewer like (cf: tests and benchmarks) that
|
||||||
|
the converted hurricane cells are the same
|
||||||
|
|
||||||
|
- deal with the layer convertions, masks ... and complete technology conversion
