-
- I have had the following problem with OCTTOOLS for a while now :
-
- I CANNOT SIMULATE PHYSICAL OCT FACETS USING MUSA.
-
- For example :
-
- I laid out a simple nand gate in "Magic" and using "mag2oct" I got a physical
-
- octfacet called "nand:physical".
-
- nand:physical has inputs "a" and "b" and output "O".
-
- The properties of the cell as shown by the command "bdnet -n nand:physical" are
-
- ________________________________________________________________
-
- MODEL "nand":physical;
-
- TECHNOLOGY scmos;
- VIEWTYPE PHYSICAL;
- EDITSTYLE PHYSICAL;
- INPUT "a";
- INPUT "b";
- OUTPUT "O";
- GROUND "GND!";
- SUPPLY "Vdd!";
-
- ENDMODEL;
-
- ___________________________________________________________________
-
- When I simulate this cell with musa, "O" is "unknown" regardless of "a" and "b".
-
- Further I can assign a value to "O", which means musa is treating "O" as any other
-
- input.
-
-
-
- ARE THERE ANY OCTTOOLS EXPERTS WHO KNOW OF A SOLUTION TO THIS PROBLEM ?
-
- I would appreciate any help you have to offer.
