increase in pattern count while ATPG DFT
Can anyone suggest on my ques? 1) I had a netlist I generated pattern say 1000 count ,later I had next version of same netlist but if you see the ET generates 11000 patterns. Can anyone update the reason for increase in teh vector count? only-2 scan clocks 2-scan reset. 1st release say 10000 flops 2nd release say 10050 flops.

setup and hold tim
Why is the set up and hold time required at all....i mean where is this extratime helped in the circuit..can u explain w.r.t to the cmos structure of the Flip Flop...as in is that some cap requires that or something else which requires that
vt of nmos
gate is responsible for the formation of channel.if the gate voltage is greater than vt then channel will form.then why the reason for getting VDD-Vt rather than VDD at the source,as VDD is not responsible for formation of channel.

fpga based alarm door security
i need to design an alarm door security by using vhdl that will embedded on fpga.this security will use keypad that need user to enter the password for security. if the user enter the wrong password for three times,this alarm will be ringing instead of block the door. please help me in designing the source code for programming the ic by using vhdl.

fast bus serial or parallel
I'm looking for a way to connect my peripheral chip with main application processors or base band chips (external connection i.e. on board). I don't want to use PHY for serial interconnect. For example, currently I’m using SPI which is fast enough (40 MHz) but I want to be compatible with other fast I/Fs. what protocols do you know that are used by main AP vendors? TI, Broadcom, Qualcom, Samsung, Marvel, etc?

E123 MUX / DEMUX Transceiver IP Core
please frd me to verilog code( which can be synthesized ) or block diagram or any details regarding the below mentioned. The E123MUX is a VLSI core that provides the E13 functions needed to multiplex and demultiplex 16 independent E1 signals to and from an E3 signal that conforms to the ITU-T G.751 Recommendation. The E1 and E3 signal an interface is NRZ only. The E123MUX can also be configured to operate as an E12 or E23 multiplexer and demultiplexer. Sixteen E1 signals can be multiplexed and demultiplexed to and from four E2 signals that conform to the ITU-T G.742 Recommendation. Alternatively, four E2 signals can be multiplexed and demultiplexed to and from one E3 signal. The E2 signal interfaces are also NRZ only. Any 4 lines of 16 E1s can be multiplexed in one E2.The E123MUX uses memory locations for setting control bits and reporting status information. Microprocessor 8-bit bus provides the access of memory locations of E123MUX/DEMUX. Feature Summary: E1 (2048 kbit/s) multiplexer/demultiplexer for ITU-T Recommendations: G.742 (8448 kbit/s E2 frame format) G.751 (34368 kbit/s E3 frame format) Multiplexer/demultiplexer converts: 16 E1s to/from 1 E3 (E13 skip mux), or 16 E1s to/from 4 E2s, or 4 E2s to/from 1 E3 (E12/E23 split mux) Select any 4 E1s to make one E2 through microprocessor interface Generates and detects E2 and E3 alarms Microprocessor input/output 8-bit bus provides split mode Intel interface

I've a speed checker circuit which is based on timer IC.This circuit mainly consists of two LDR and two leser and seven segment display for showing the counting.That counting will give the speed/hr by using a formula i.e speed=3600/counting.Now my question is ,how can i convert that counting into visual unit.Means that speed should be display by using 7-segment.
