Aldec expands advanced verification capabilities of its ALINT-PRO™ design rule checking solution

Assure robustness of Finite State Machines and Reset Domain Crossings – via early static checks

Henderson, NV – January 17th, 2018 –  Aldec, Inc., an industry leader in Electronic Design Verification, has expanded the rule-checking capabilities of its popular ALINT-PRO™ tool in response to growing complexity of large-scale modern FPGA and ASIC designs. Rules new to the 2017.12 release of ALINT-PRO™ assure the integrity of a design’s Finite State Machines (FSMs) and help identify possible Reset Domain Crossing (RDC) issues.

“In large designs it is typical to have several FSMs controlling the workflow. However, despite the use of consistent HDL patterns to describe the FSMs, the number of coding mistakes made in the RTL descriptions is often high” observes Sergei Zaychenko, Aldec Software Product Manager. “At Aldec, we are aiming to provide the most comprehensive rule coverage to help designers create reliable, portable, and highly readable state machine descriptions.”

Verification of RDCs, also new to the 2017.12 release of ALINT-PRO™, targets issues with complex SoC reset strategies and circuits with dynamically switchable regions. For instance, a harmless looking data transfer between registers with unrelated asynchronous reset controls may end with unrecoverable metastability, unless properly addressed at the RTL design phase.

ALINT-PRO 2017.12 Highlights


ALINT-PRO™ is a design verification solution for RTL code written in VHDL, Verilog and SystemVerilog, which is focused on verifying coding style and naming conventions, RTL and post-synthesis simulation mismatches, smooth and optimal synthesis, reliable and portable FSM descriptions, avoiding problems on further design stages, clocks and reset tree issues, CDC/RDC, DFT, and coding for portability and reuse. The solution performs static analysis based on RTL and SDC™ source files uncovering critical design issues early in the design cycle, which in turn reduces design signoff time dramatically.

The 2017.12 release of ALINT-PRO includes numerous new features, usability enhancements, and performance optimizations. For additional information, tutorials, free evaluation download and What’s New Presentation, visit
