Why latches are not preferred in any design?

1. Why LATCHES are not preferred in any Design??

2. Is there any case, where Latches are used effectively??

Latch -reg.

Hi
Latch is more sensitive to noise means that whenever there is change in the input output will change; that will give race condition in the output.

Latch -reg.

Latches alwaysd preffered in design.
Latches supply the low pin numbered desings.
Master-Slave vs...
Ex.
MCU select chipA with CS pin
MCU send dataA to chipA over a Latches IC
MCU disable bus to chipA
and repeat for chipB
in progress for chipB, ChipA dont forget its inputs

Latch -reg.

the main reason is lack of EDA tools to support large design.

Latch -reg.

flip-flop are used because it's triggered by edge of clock,it can sustain noise than latch

Re: Latch -reg.

latch can be found in cpu design.
buf reg are more popular in eda,because it suite the tools such synthesis and STA
well
