| The
customer
The client is one of Taiwan's largest and most
successful fabless semiconductor companies and
develops ICs and SOCs for communications networking,
PC peripherals, digital imaging, and other applications,
and is the world's number one provider of Ethernet
and Fast Ethernet ICs. In 2001, the client was
named as one of Forbes magazine's "International
200 Best Small Companies." It is located
in Hsinchu, the "Silicon Valley" of
Taiwan.
The challenge
The client had a 1394a Analog PHY. They wanted
the 1394a Digital PHY from Wipro so that he can
interface their 1394 Analog PHY to develop complete
1394a PHY chip and market it. The client had a
special requirement regarding the registers which
can be read or written from outside for configuring
the analog design parameters. Their 1394a Analog
PHY had 8 bit interface to the 1394a Digital PHY,
where as the Wipro 1394a PHY had 1 bit (serial
interface) to the 1394a Analog PHY.
The solution
Wipro provided the option of configurable 1394
Physical Layer IP where the 1394a Digital PHY
can be configured to interface with the 1394a
PHY in either serial mode (1 bit) or parallel
mode (8 bit). Wipro also did customizations to
the 1394a Digital PHY so that some parameters
can be configured to suit to the Client 1394a
Analog PHY. This helped the customer to use Transmit
path interface with high speed logic in digital
and Receive path interface with high speed logic
in analog. Wipro also provided knowledge transfer
on the PHY-LINK interface to the Client. Wipro
provided the registers and the read write access
through the test mode debug interface in the existing
IP.
Wipro also provided the configurable ports option
for 1394a Digital PHY where the number of ports
can be configured to 1 to 3 ports.
Wipro has done integration of the 1394a PHY with
the 1394a AVLINK IP so that the client can develop
Integrated AVLINK chip for DVD writer market.
The benefits
The client is able to successfully Integrate Wipro’s
1394a Digital PHY IP with its own 1394a Analog
IP along with the Wipro’s 1394a AVLINK IP.
The 1394a Digital PHY is suitable for his future
applications with either 1 bit or 8 bit interface.
The Integrated testing of the 1394a AVLINK IP
with the 1394a Digital PHY by Wipro also gave
the Client time to market advantage.
