write a single assertions with constraints embedded

My specs say that PLL should fire a loss of lock interrupt within 8 clock cycles for loss of lock condition in non-bypass mode Now i have one assertion which states loss of lock interrupt comes with 8 clock cycle w.r.t loss of lock condition constraint is that we should be non bypass mode Is it good...

Why Can’t You Write My Assertions for Me? - Part 1

As regular readers know from previous posts , I have a lot of background in assertion-based verification (ABV) and how assertions are used in simulation and formal analysis. There has been a lot of growth in the use of both assertions and formal since I was first involved in these technologies in 1999...

Video: Formal Verification Service Provider Oski Technology at DVCon 2011

While there was a lot (justifiable) buzz around the UVM 1.0 release, formal and assertion-based verification (ABV) technologies and methodologies also had a great showing at DVCon 2011. Beyond the many papers and posters on this topic, further evidence of formal verification growth is the emergence of...

how to write formal assertion for mentioned property

I have specs which says PLL shouldn't lose lock when the reduced frequency divider(RFD) is changed As I understand we should check that RFD or it's delayed value should not be a part of equation for PLL_LOCK Can we write any assertions for the same and prove it formally ? Thankx in advance Ashish

Save The Date: Free Webinar on Automated SoC Connectivity Verification This Thursday March 24

We interrupt our technically oriented blogging to shamelessly promote a free webinar we are giving on SoC Connectivity checking this Thursday March 24 at 10am-11am Pacific time. At first glance, this topic doesn't seem like such a big deal - after all, checking IP-to-IP and point-to-multi-point connections...

User Experience: Optimizing Power and Area With Formal Verification

Formal verification can be a powerful tool for low-power design optimization, according to a paper authored by Cadence and Freescale and presented at the recent DVCon conference. The paper showed how formal property checking can validate whether retention flip-flops are controllable, and identify those...
