- hi all,
-
- unfortunately, i have to do the following: translate an edif netlist into
- verilog using the cadence tool e2v (formerly of gateway design automation).
- the edif netlist was generated by the max+plus II compiler of altera corporation.
-
- now: my problem is that the delays in the edif netlist get lost in the
- translation. i know less than nothing about edif, but what i am seeing is
- that in the edif netlist, the delays are all on instances of a special cell
- called "DELAY". i have generated two versions of the edif netlist: in the first,
- the delay is specified using the property "TPD". in the second, the delay
- is specified using "portDelay".
-
- when the delay is specified using property "TPD", i have tried the "map property"
- statement in the .map file of e2v. however: it seems i need to choose one of
- TPLH, TPHL, etc. - but i apparently want all of them. how can i do this? in
- any case, i get warning messages of the following format:
-
- (?E2V) ***WARNING*** Property TPD mapped to TPLH (in cell NTSC in library ALTERA) not relevant for a module instance OR2_96
-
- and the resulting verilog netlist (using +force) contains no delays.
-
- when the delay is specified using "portDelay", i get error messages of the
- following format:
-
- (?E2V) ***WARNING*** Feature not supported : portdelay cannot be backannotated using portinstance port \1 of instance AND3_8 : cell NTSC lib ALTERA
-
- and again, the resulting verilog netlist (using +force) contains no delays.
-
- does anyone have a clue?
-
- alternately, does anyone know how i can get the altera compiler to use
- "pathDelay", which seems to work fine, rather than "portDelay"? or to put
- the delays on the cells themselves rather than on these silly cells called
- "DELAY"?
-
- thanks,
-
- cindy.
