问了我的经验
timing问题(max time, min time)
clock skew, jitter
Process Variation related to max time and min time
what corners to use for max time and what corners to use for min time
How does the current behave with temperature
6bit comparator, how to implement
RC: how to improve RC delay
我就我想的jitter的概念和他想的不一样. 很多问题就答对了, 但是理由不充分. 说这
周给feedback.

他们B2—I94十一月到期，由于突发原因现在要延期。
我想在线给他们申请。谁能提供链接。
我印象中是不是只要我提交了在线申请，他们就可以合法居留下来等批准通知。请确认。

Quote:
"It Renesas] is also farming out some manufacturing of automobile
controllers to GlobalFoundries, a contract manufacturer in Singapore that
has produced microcontrollers in the past
"In automobile microcontrollers, Renesas’s main competitors include
Freescale Semiconductor and STMicroelectronics.

(b) microcontroller
http://en.wikipedia.org/wiki/Microcontroller
(a self-contained system with a processor, memory and peripherals; The first
computer system on a chip optimized for control applications was the Intel
8048, released in 1975, with both RAM and ROM [read-only memory] on the same
chip; Nowadays microcontrollers are low cost)
Quote: "A typical home in a developed country is likely to have only four
general-purpose microprocessors but around three dozen microcontrollers. A
typical mid-range automobile has as many as 30 or more microcontrollers.
They can also be found in many electrical devices such as washing machines,
microwave ovens, and telephones.

(e) Ricoh is headquartered at Tokyo.
Company History. Rocoh, undated.
http://www.ricoh.com/about/company/history/
("Ricoh’s origins date to a decision of the Institute of Physical and
Chemical Research to commercialize the fruits of its R&D by setting up
Rikagaku Kogyo. In 1936, Rikagaku Kogyo established [理研感光紙株式会社,
hence the current name 理光] Riken Kankoshi Co., Ltd. (renamed 理研光学工業
株式会社 Riken Optical Co., Ltd., in 1938, and Ricoh Company, Ltd., in 1963)
, to manufacture and sell sensitized paper. The Company started its camera
business in 1937.")
