First Pass Silicon Realization Experience, Everytime

Physical Implementation business unit within BlackPepper is one of the seasoned groups within the company, housing a highly experienced world-class team that has churned out multiple first pass silicon’s in advanced technology nodes for varied class of customers across wireless, automotive, connectivity, consumer applications, medical, IoT markets. This team has the experience of taking a design from early premature RTL stage to supplying end silicon’s volumes to customers.

They have engaged with customers early-on in their design flow and enabled them to define/improvise their designs, flow there-in reducing their design/implementation cycle time. This innovative thought process and engagement style has provided a huge monetary benefit for the customer and business continuity, fresh opportunities for BlackPepper.

The team has worked on cutting edge technologies, designs and have been innovative in their offerings for each and every customer. The group has been constantly upgrading their knowledge base and can support customers in the following areas

  • Experience of handling silicon’s in Wireless, Automotive, Connectivity, Consumer Applications, Medical, IoT domains.
