when i finish elaborate step using dc, i get GTECH netlist. i set dont_touch in this module, and then synthesize this module or synthesize the upper module, i want to know that whether i can get the gatelist that have mapped to target library?

If the module to which you applied constraint dont_touch is a library specific cell instatiated module.. it will be fine...(means that module is already a netlist for target libary) ,otherwise the GTECH netlist wont be mapped into target library...
BUT i find that the GTECH cell that no instantiated to target library cell had not mapped to target library.i get the gate netlist including GTECH cell.
right, for some simple logic, you need direct instanciate library cell in RTL, and set dont_touch before compile.
e.g, clock gating cell, or clock muxplixer.
If you want to retain the module don't touch in top level synthesis, you can do the following:
1. set current design to that sub-module.
2. Do synthesis on this module.
3. Set don't touch attribute on this module or set current design to top module and apply don't touch on that instance.
4. Do top level synthesis.
hi u can do like this
u can easily convert the gtech components into ur desired library components
just in DC compiler make target library( which library ur using now )
and read the file which have gtech componets and do the follwing steps
this will give the design with ur liberary componente
then using that file u can do ur synthesis
the steps to convert the gtech componenets
1. make the traget library
2. read_file -
3. current_design module name
4.link
5. give the translate command
6. write file in verilog format
after this u can use this file
Pls find the related details in translate comment in DC tools directory
Dear sir :
can you help us .. .about it , if you really know the link of it or you have got it in you hand..
becos .. solvenet .. need password ...anyway ...
