SOC Stability in a Small PackageFrom GreenIPCore There are some IPs in SOC which are of general use and malfunction on them impacts a entire SOC. We Identified these IPs and analyze impact on SOC due to their malfunction–
A malfunction on these IPs disturb entire SOC in a way that Software cannot handle it and would not be aware that there is malfunction impacting. 1. Clock and Reset generator If there are malfunction within Clock and Reset Generator and there is some issue in RESET GENERATION – And if reset are generated in wrong times then -
And if Reset is triggered but the reset duration is not right –
And if reset is triggered to Half the SOC but remaining half is still not reset -
And if there are issues in CLOCK GENERATION and somehow clock configuration is disturbed then –
2. Timers Usage of times is quiet important in a system. Timers can be configured to generate different interrupts at different times. System needs it for different applications like –
There can be so many use Interrupt has in a system. But if this such a important IP gets corrupted by any means and start generating interrupts at wrong times or start generating wrong timestamp values. The entire system will start misbehave. If the Interrupts are generated Early due to corruption in start value following can be impacts –
If the Interrupts are generated late due to corruption in start values following can be impacts –
And if Interrupts are NOT generated due to corruption in Mask values following can be impacts –
Now one thing is sure one cannot make a high reliable product from such an Unreliable Current Electronics. 3. Watchdog A watchdog is a very important IP Component of SOC and System use it as a Timeout Counter to ensure if any Application or OS hangs, an interrupt trigger from it will ensure a reset on that IP block or System. System keep also a watchdog timeout to ensure hardware components like Backbone, Processor and other reliable components are running fine. And if they lock or Misbehave in any scenarios, watchdog will fire interrupt to take out system to reboot. Any Corruption in watchdog will make –
The Unreliability in this component makes entire application or System into unreliable state as no one can ensure that a certain reliable service is definitely going to work in all possible conditions. 4. Interrupt Controller A interrupt Controller is also a key element in the entire working of SOC and application. A interrupt controller is used to gather different Interrupts from different IPs within a SOC and pass it to Processor to switch to Exception mode and run certain mapper ISR for that Interrupt. Any Corruption in this IP will make –
In all the cases above, the Processor working would be distracted. The Wires connected to this IP are coming from all the places from the SOC and are long in nature making it more easily distracted by electromagnetic noise. So, we see by evaluating these Four IPs are very important for a SOC to ensure the services are running fine. Whatever we do in Software, if any of these four IPs misbehave, the entire system fails and unable to provide reliable services to the User. We at GreenIPCore Built these IPs with A VERY STABLE AND HIGH RELIABLE electronics. It will allow -
This will make the SOC run High stable in real time Application. Improve the Product Value over time. GreenIPCore, Re-constructed these four IPs with new High Reliable Technology and Constructed them for very high reliable working.
One can see the issues in this youtube videos - Effect on of Noise on Calculators (just to give you a view of Noise effect) - Developed New type Counter which is more Stable Developed New Shift registers Testing Demo Following is Sample video showing working of Full High Reliable Timers and is compared against Standard timers - We offer license for these IPs under SOC Stability Package. These four IPs are Fully tested and are available Soft Silicon Verilog Codes available with wide verity of configuration.
