I want to do a HAL analysis on VHDL design.What are the procedure and steps for that?/
Please tell me
If you compile your design with "irun" already then you can just add the "-hal" switch, then use the "ncbrowse" tool to review the lint messages via a GUI.
Alternatively if you use ncvhdl/ncelab/ncsim, then after elaboration you can invoke "hal" and pass the snapshot name on the command line to HAL.
In reply to StephenH:
apply command "nclaunch"
select a design
select all vhd files in selcted design and press ncvhdl option .
After this it give various errors .. How to resolve that?
How to elaborate particlar design?
In reply to sonam20:
How to get sanpshot of elaborated design.??
Without seeing your compilation log there is no way to know what those VHDL errors are, nor can we guide you to resolve those unknown errors. I would recommend talking to one of your colleagues to get the required compilation order for the files, as well as any specific switches like VHDL-93 options etc.
Alternatvely you could post the log file here, or go to http://support.cadence.com/ and file a service request asking for help to run HAL.
I found these type of error after compilation. Please tell me how to resolve them.

The logical library name indicated is not mapped to a design library.
Section [11.2] of LRM [87 & 93]. A user option file entry of the form:
must be present for each logical library name L.

This message, which seems to be the cause of most of the following error messages, is saying that the parser doesn't know where to look to find the compiled objects for the BB_PKG package. It doesn't know where the library called "DESIGN" was stored.
Cadence tools use a file called "cds.lib" to map logical library names to physical disk locations. Search for "cds.lib" in the NCLaunch documentation for help in setting up that mapping file.
