help for ius6.2 simulation?
when i simulate my verilog design using the following command:
ncverilog hello.v
some ERRORs occur:
ncverilog(64): 06.20-s005: (c) Copyright 1995-2008 Cadence Design Systems, Inc.
file: hello.v
module worklib.hello:v
errors: 0, warnings: 0
Caching library 'worklib' ....... Done
Elaborating the design hierarchy:
Building instance overlay tables: .................... Done
Generating native compiled code:
worklib.hello:v <0x3eff1d51>
streams: 1, words: 476
Loading native compiled code: .................... Done
Building instance specific data structures.
Design hierarchy summary:
Instances Unique
Modules: 1 1
Initial blocks: 1 1
Simulation timescale: 100ps
Writing initial simulation snapshot: worklib.hello:v
ERROR: can't determine installation root.
can't create rooted path to arg0 "ncroot"
using current working directory or $PATH
when i use "irun hello.v",it has the same errors.
i have set the environment variable CDS_ROOT to ius62 installation directory
