Design Feature
It was a complex project as this involved the first ever GDDR6 chip test using 8LPP technology. It involved additional requirements like
IP Max frequency of 6GHz and controller frequency of 1.5GHz
Hierarchical based implementation with SOC and multiple Hard-macros
Each block having >1 million instances
Outcomes
- Ownership of Time Constraints including the External IO interfaces
- Alignment with Package team on the bump placement
- Regular interaction with RTL and Program Management team based out of Korea
- Very tight/difficult to meet 6GHz and 1.5GHz frequencies
- RTL development was in parallel to the PnR execution
- RTL development was in parallel to the PnR execution
