Part 4: The 2020 Wilson Research Group Functional Verification Study
This blog is a continuation of a series of blogs related to the 2020 Wilson Research Group Functional Verification Study (click here).
FPGA Verification Effort Trends (Continued)
In my previous blog (click here) I discussed verification effort trends in terms of project time spent in verification, as well as increasing headcount as indicated by the rising mean peak number of design and verification engineers working on FPGA projects. In this blog I continue the discussion of FPGA verification effort trends by looking at where engineers spend their time.
Where FPGA Design Engineers Spend Their Time
Verification engineers are not the only project stakeholders involved in the verification process. Design engineers spend a significant amount of their time in verification too, as shown in fig. 4-1. In 2020, design engineers spent on average 53 percent of their time involved in design activities and 47 percent of their time in verification. However, when compared to 2014 and 2016, the data indicate a trend showing that FPGA design engineers are now spending slightly less time involved in verification tasks. There are two reasons for this trend. First, many FPGA projects have added verification engineers to their teams, which means design engineers can focus most of their effort on design. Second, in general, there has been increased adoption of larger, more complex FPGAs, which has increased the design engineer’s workload.
Fig. 4-2 shows where verification engineers spend their time (on average). In general, there have been no statistically significant changes in the FPGA results during the period 2014 through 2020.
Our study found that FPGA verification engineers spend more of their time debugging than with any other activity. From a management perspective, this can be a significant challenge when planning future projects’ effort and schedule based on previous projects’ data since debugging is unpredictable and varies significantly between projects.
The key takeaway here is that a significant amount of engineering time is spent in the verification process when you consider the combined design and verification engineering time.
In my next blog, I shift the focus of our discussion from verification effectiveness and effort trends to FPGA verification technology adoption trends.
