Network awk script issue
Thanks Ctgsnb

Yeah I also tried like this and it worked perfectly fine with one file
but in another file I dont have
Code:
;

after the
Code:
}

, in that case what to do ?

Code:
 
pin (RXEDF) {
input 
output 
}
 pin (RXEHRR) {
input kdk
output kdkdk 
}
pint (RXHERT) {
input jdjd
output kkd
timing () {
   rise_constraint (setup_template_2x2) {
         index_1 ("1.000, 195.000") ;
   }
fall_constraint (setup_template_2x2) {
         index_1 ("1.000, 195.000") ;
   }
     }
timing () {
       related_pin : "TXHDCLK" ;
       timing_type : hold_rising ;
rise_constraint (hold_template_2x2) {
index_1 ("1.000, 195.000") ;
}
fall_constraint (hold_template_2x2) {
index_1 ("1.000, 195.000") ;
}
}
}
pin (RXCER) {
input ioti
output nfnf
}

Any suggestion for this ? no blank lines as well as no
Code:
;

Thanks

Code:
sed 's/^pin/#&/' input | tr '#' '\n' | sed '/RXH/,/^$/d'

note that this code will add an empty line before every lines beginning with 'pin'
you can then delete them again with a grep -v

note that instead of # you should choose a charactere that appear nowhere else in your code (µ,§, ....) up to you to choose a right one

Try this:
Code:
awk '/RXH/{f=1}; f{c+=/}/?1:/{/?-1:0}; !f; f && !c{f=0}' file

Code:
awk '/RXH/{f=1}; f{c+=/}/?1:/{/?-1:0}; !f; f && !c{f=0}' file

Explanation:
Code:
/RXH/{f=1}  	If the line contains RXH, set the flag f
f{c+=/}/?1:  	If f is set and the line contains a "}" increase counter c ..
/{/?-1:0}  	..else if the line contains a "{" decrease c
!f  	print the line if f is not set
f && !c{f=0}  	If f is set and c == 0 unset the flag

@jaita

Note that this code assume your file has its { and } correctly formated :

If somewhere in your code you have

This kind of things :

Code:
timing () {   rise_constraint (setup_template_2x2) {
         index_1 ("1.000, 195.000") ;
   }
}

instead of

Code:
timing () {
   rise_constraint (setup_template_2x2) {
         index_1 ("1.000, 195.000") ;
   }
}

This may lead to unexpected results (this is just an example of bad formating)

If several { are on the same line whereas the corresponding } are on differents lines, the counter may be mistaken.

To secure Franklin code, you should count the number of { and } per line and increment and decrement the counter accordingly for every hit
