eda_NP.jpg" HSPACE="7" ALIGN="RIGHT">Tharas Systems Inc., a provider of hardware-assisted verification solutions, announced its support for Verilog 4-state logic simulation in its Hammer 100.

Delivering what the company touts as the EDA industry's only hardware accelerator with 4-state support, the Hammer 100 can now detect and propagate 4-valued logic"0," "1," "X" and "Z" similar to a Verilog software simulator. According to Tharas, this significantly shrinks the time-to-performance while enhancing overall verification accuracy.

Traditionally, engineers have utilized the 4-state capability of the Verilog simulation language to pessimistically model design elements, said the company. This capability helps uncover issues associated with reset logic, random initialization, bus conflicts, un-initialized registers and ATPG-based verification. In the past, since hardware-assisted verification tools only supported 2-state logic ("0" and "1"), engineers had to simplify 4-state dependent models to match software simulation results especially in the test bench, Tharas added.

"With 4-state support, Tharas offers the most accurate hardware-assisted verification solution in the industry," shared Rahm Shastry, president and CEO of Tharas. "Migrating designs from simulation to hardware-assisted tools often requires remodeling ASIC cells such as pads, memories and tri-state-based logic. This breakthrough capability eliminates re-modeling of such cells or re-writing of 4-state dependent initialization sequences."

The Hammer 4-state capable compiler option is available for production use immediately on Solaris and Linux-based platforms. It is an add-on option to Hammer compiler version 4.0. List price for a perpetual license of this option is $20,000. It is also available through T-FORCE, Tharas' Flexible On-demand Rental Collaborative Environment program.
