Hi All,

I am doing code coverage, receiving following error;

ncelab: 14.10-s014: (c) Copyright 1995-2014 Cadence Design Systems, Inc.

Elaborating the design hierarchy:
ncelab: *W,ICFUC: Unknown Command on line 2 of file mentor.ccf.
ncelab: *W,ICFUC: Unknown Command on line 3 of file mentor.ccf.
ncelab: *W,ICFUC: Unknown Command on line 4 of file mentor.ccf.
ncelab: *W,COVEOP: mentor.ccf:7 "-all" with set_expr_scoring is an expensive option as it selects all the expressions in the design. It has been deprecated and will not be supported in subsequent releases.
ncelab: *W,ICFUC: Unknown Command on line 11 of file mentor.ccf.
Caching library 'worklib' ....... Done
ncelab: *E,COVMDU: The design unit 'musbmhdrc' has multiple top-level instances in the design enabled for coverage.
ncelab: Memory Usage - 36.2M program + 20.7M data = 56.9M total (Peak 56.9M)
ncelab: CPU Usage - 0.0s system + 0.0s user = 0.0s total (0.1s, 92.2% cpu)
TOOL: ncelab 14.10-s014: Exiting on Jan 09, 2018 at 12:09:19 IST (total: 00:00:00)

This is the .ccf file;

select_coverage -block -expr -toggle -file ./../../rtl/
select_coverage -block -module musbmhdrc
set_assign_scoring
set_expr_scoring -all
set_expr_coverable_operators -all
set_branch_scoring
set_statement_scoring
set_implicit_block_scoring -off
set_explicit_block_scoring -off

where musbmhdrc is the top design name and musbmhdrc_lpm_hostrst is the respective testcase. Can anyone help to proceed further ?
