Hi,

I have IC614 installed. DRC and LVS are running fine but there is a problem facing during QRC run. Before the details of the error, please have a look at the configuration of my current setup:

Platform: Cent OS 5.8 [64 bit]
Installed Cadence Products: IUS08.20.017, IC06.14.512, MMSIM10.11.218, ASSURA4.12-614
Technology: UMC_180_ANALOG [64bit] (1.8-3.3V, Mixed-Mode, 1Poly6Metal Process)

I have configured .cdslib. assura_tech.lib, .cdsinit and .bashrc files to have my cadence installation running fine.

To verify the whole setup, I just created a simple inverter (in Virtuoso Schematic Editor XL), did a schematic-level simulation (in Analog Design Environment XL), did its layout (in Virtuoso Layout Suite XL), did DRC and LVS (in ASSURA).

Up to this point there was no problem.

After this when I tried to perform a QRC run, it failed. The error is:

I am clueless about the reason behind this error. Please help me to resolve this issue as soon as possible.
 

Hi Samiran_dam,

I got similar problem as you asked:

*WARNING* (TECH-230035)

Can you tell me how to fix this warning, please? Thank in advanced.

In the QRC setup window, you will see Setup tab (the first tab). In that setup tab, un-check the "Enable CellView Check" option. (attached is the screen shot). Then you will not get this error. The errors will be converted to Warnings and that will not be a problem.

Thank samiran_dam,
I follow your instruction. However, the problem is still there.
I use Cadence IC 615, and the "Enable CellView Check" option is un-checked as default.

The attachment that you have sent suggests that you have not selected the Technology and the corresponding Rule Set. I think that is the reason why u r getting the error.
 
Thank Sam,
I think you may be right. But I want to ask one more question. How can I fix it? When I trie to create my own library (my_lib) with "Attach to an existing techfile" option, the CIW displayed this warning. It means that I did not go to run QRC step.

I did not get your problem. Are you trying to say that when you are creating a new library (say, "my_lib'), and when you select "Attach to an existing techfile" option you are not seeing any available technology library to select from? If that is the case, then you check you cds.lib file.
 

Hi Sam,
Actually, I can choose technology file when I select "Attach to an existing techfile". But I don't know why the warning is showed?
