View Full Version : [ubuntu] Verilator Installing Problem

April 3rd, 2010, 03:09 AM
Hi..I am trying to install Varilator (Verilog simulator) I am getting this kind of error msg

le test_sp/Makefile_obj ; do \
/usr/bin/install -c $p /usr/local/share/verilator/examples/$p; \
/usr/bin/install: cannot stat `test_sp/*.[chv]*': No such file or directory

Add to your startup file (for bash or csh, as appropriate):
export VERILATOR_ROOT=/home/parthiv/Desktop/verilator-3.801
setenv VERILATOR_ROOT /home/parthiv/Desktop/verilator-3.801 ; export VERILATOR_ROOT

See 'verilator.txt' for documentation.

Cycle accurate models in C and SystemC are becoming an increasingly important part of the verification process, particularly for SoCs with performance critical embedded software. They represent a software friendly compromise, offering higher performance than traditional event-driven simulation, but greater accuracy than hand-written instruction set simulators (ISS) and transaction level models (TLM).
Typically such models follow 2-state, zero-delay synthesis semantics, offering an early insight into the behavior of the synthesized design. Applications include:

Detailed performance analysis of systems, based on the actual hardware implementation running with its embedded software.
Implementation of low level firmware, such as board support packages codecs and specialist device drivers, which rely on exact behavior of SoC peripherals.
Software optimization. This can be particularly important for codec development, where the performance depends critically on interaction between processor, memory, cache and MMU. In such scenarios, estimates by ISS and TLM can be out by a factor of 3, resulting either in wasted silicon, or chips that cannot meet their required performance.
