flexlm multiple licenses
In winxp how to set multiple license files in flexlm?
I'v set several license files in Flexlm manager, separated by ";", but it dosn't work.
Flexlm can not recognized them at all.
And I'b set several license files for LM_LICENSE_FILE too. There is no conflict, which...
Basic Layout doubt
I don't know this very exactly. Let me guess.
Maybe sig b is in the middle of the parallel wire group, so both a and can interfere b by crosstalk. Therefore, sig b have more delay than a and c. Change the drive strength of b twice than a and c might overcome this question.
Re: floorplan question
I always use the top 2 layers for core ring and power straps. but in some design, i found that the top layer was always preserved, why? what is the advantages?
set_structure true is the default option when compiling with DC, you can set_flatten true before compling and you'll get a two-level logic in structure sum-of-product
floorplan question
when floorplanning, which metals should be use for core rings and power strapes? top two layer or bottom two layer?
or others ? and what are the advantages and disadvantages of the these stratagems?
regards
power compiler can tell you the switch power, internal power(short circuit power), both of which are dynamic power. And static power(leakage power) can be caculated too in power compiler.
i know, the function is not hard to understand and it's easy just to build it with a comparator and a traditional complementary adder.
what I really want to know is how to implement it efficiently.
any advice?
subtract a positive number from another, and use a sign extension format to represent the result, the msb is the sign bit.
For example
0011-0010=0001
0010-0011=1001
Can this subtractor be implemented efficiently as a complementry subtractor?
