hello
i am shariff a student form india. i have just started working on
asic design using Mentor Graphics ICSTATION.

I am familar with Design Architect, EDLO, ICSTATION using ADK
KIT,and a little bit of IC STATION.
so far i have successfully created and verified a layout using
Automatic routing and palacing from HDL(converting into EDDM and
genretaing schematics and viewpoints) and back anananotted the
design.

I am preseently trying to do SDL and have comes across so
problems. i was not able to place the transistor . i got the
following erroe message .

// Error: $set_device_info_for_dynamics returned error status at
line
16453 of file /soft/asic_proj/sdl/module_ic.ample within function
$mos_parameters (from: Uims/Ample/Ample_eval 1D)
// Error: Loadable Module "devices": Mos type, a, is not defined in
the process. (from: Ic/modules/general 01)



just to verify tht i have made no mistake in the flow . i am
descibing in brief wht did
1) i first created a small design(inverter) using design architect
and registed the model. { the mos transistors choose we from
$ADK/lib/sdl. i have also tried doing with platte on the right hand
side but same prob)
2) then i created the viewpoints using adk_dve and verified it with
dve_ic
3)and created the cell using creat cell from icstation,
process file: $ADK/technology/ic/ami05
rule file : $ADK/technology/ic/ami05.rules
eddm source : $MGC_WD/inveter/sdl(point to the sdl viewpoint of the
component)
4)set the cell configuration to connectivty editing and open the
logic
5)then executed pr() fro placing vdd and ground.
6) then choose the transitor on the schematic and pressed instance
and i am struck at this point i got the error message

// Error: $set_device_info_for_dynamics returned error status at
line
16453 of file /soft/asic_proj/sdl/module_ic.ample within function
$mos_parameters (from: Uims/Ample/Ample_eval 1D)
// Error: Loadable Module "devices": Mos type, a, is not defined in
the process. (from: Ic/modules/general 01)

i have checked the process file ami05.proce_ic though i could not
make any head and tail of it but there some entries for pmos4
,pmos,nmos,nmos4.all these entries were starting with some numbers
4/6. i have tried changing the transistor in the schematic but no
sucess.
in sdl setting the filter was set $device_filter and search path
to $ADK/technology/ic/amio5_via
i am not sure wht this $device_filter is but i guess it is used to
search the device layout. i have read the some pdf's provided by by
MGC it mentions something abt device genertor but i couldn't find
and setting or any other thing regarding device genrator.

i hope someone get me out of this fix i have been trying this for
quite sometime our asiclab is basiclly newly setup and noone
anything abt it, it is left up to students to learn themselves.
therefore i need a lot of help for some people who have already
worked on it.

thanking in anticipation
