Hi,
I am trying to synthesize my design using RTL compiler. when i execute the command
synthesize -to_mapped
I got the below error
Warning : Could not find a scan-equivalent cell. [DFT-510]
: Library-cell ’/libraries/tsmc_25/libcells/DFFHQXL’ cannot be scanned.
: A scan-equivalent cell was not found. A potential scan-equivalent library
cell is considered not usable if it has a ’dont_use’ or a ’dont_touch’ attribute
set to ’true’ in the .lib files. In this case, use ’set_attribute preserve false
<scan_libcell>’ and ’set_attribute avoid false <scan_libcell>’ to make the cell
usable. A potential scan-equivalent library cell is excluded if it does not follow
the Scan Cell Requirements described in the ’Library Guide for Encounter RTL
Compiler Ultra’. This requires fixing the library.
I am using libraries from Nangate (45nm). I can see the scanFF in the library files.
I tried some troubleshooting steps from Cadence documentation...
set_attribute preserve false scan_libcells
set_attribute avoid false scan_libcells
I tried this on all the scan cells in the library, but dint help.
Any one faced this issue?? Any ideas/inputs?
Thanks in advance.
