请问electrical/analog verification 职位一般问点啥?
我是FRESH GRAD.有一些电磁,信号完整性的背景,VERILOG, VB不会,
对于FRESH的话,问点啥呢。 谢谢 | T******T 发帖数: 3066 | 2 这个position有点奇怪啊,不是hw test ? | d******e 发帖数: 200 | 3 TroubleT, 你好,我说的这个不是hw test, 是intel的electrical validation职位,
简介上说是测试after silicon的cpu和chipset的性能。可能会用的仪器有示波器,TDR
等等。请您帮着预测一些关于面试的可能问题,谢谢! | T******T 发帖数: 3066 | 4 哦,看起来是device validation, device characterization 之类的吧,在大.com公司
里面的职位一般是Analog or Digital DVT。 问题俺想想看吧。
TDR

| d******e 发帖数: 200 | | T******T 发帖数: 3066 | 6 俺觉得可能会问:
1)ATE 的问题,DFT/functional pattern generation/debug. Boundary scan,
at speed testing techniques, PVT on the ATE and Shmoo plot.
2) Analog/Mix signal circuit validation methodology for embedded LDO,
PLL, DAC/ADC, Digital/Analog I/O cells (slew rate control, drive
strength control validation).
3) Power/Ground integrity and its effect on the device, noise and
voltage level under min/max load, low<->high switching supply.
4) I/O characteristics validation, such as VIH/VIL,VOL/VOH, IOL,IOH,
I/

| T******T 发帖数: 3066 | 7 Sorry, forgot about that TDR thinging you mentioned. Unfortunately, I
have not used a TDR scope or TDR probe before. I'm assuming it helps to
identify interconnect signal reflection due to impedance mismatches.
So, might want to study up on Signal Integrity and transmission line
theory subjects.
