In our previous blog entries, Improving QoR with report_qor_suggestions in Vivado and Design Closure with RQA and RQS, we learned how Report QOR Suggestions (RQS) helps in design closure with clocking, utilization, congestion and timing suggestions.

In this entry we cover the “RQS_CLOCK-12” clocking suggestion and how it helps in timing closure.

We have learned through previous blog entries how Report QoR Assessment (RQA) and Report QoR Suggestions (RQS) can be used to improve the overall design analysis and timing closure experience of your design.

This blog entry will cover how to use RQA and RQS together in the implementation process using one specific design example.  

Report QoR Assessment (RQA) details how likely you are to achieve your design’s QoR goals.

If the news back from the command is not what you were hoping for, this blog entry contains some additional information on what you can do next. This entry is great for new users of the commands, and should also be very handy for experienced users..

This blog entry touches on how solving methodology issues will help you to make more effective timing closure decisions.

A lot of FPGA designs can struggle to hit their required performance targets. The reasons for this are varied but here is a list of some possible causes:

• Not following the UltraFast Design Methodology
• Poor timing constraints
• Over utilization
• Too many control sets
• Sub-optimal clocking
• High number of logic levels for target performance
• Bad floorplans
• Routing congestion
• Tool optimization limited due to constraints

In this blog find out how 'report_qor_suggestions' can enhance your productivity by automating solutions to problems that limit FPGA performance.
