IspLever5_1, Can I specify the I/O pins for Gal22V10 to meet a specific design?

Question

File was generated from schematic input ABEL isplever5.1:

This is a "nothing-special" Shift register (Din/CLK), and tri-state output: EN.

Output pins are Labeled (KP_0 to KP_9) should be mapped to (Q1 to Q10) and pins: (23 to 14) in order

INPUTS: CLK(1), Din(2), EN(3)

OUTPUTS: KP0(23), KP1(22), KP2(21), KP3(20), KP4(19), KP5(18), KP6(17), KP7(16), KP8(15), KP9(14) 

^^^ desired sequence ^^^

However: When it autoassigns pins, it goes from PINS 23-> 14:

KP_0, KP_2, KP_4, KP_6, KP_8 (even- ascending)
KP_9, KP_7, KP_5, KP_3, KP_1 (odd - decending)

See diagram (attached):

QUESTION: Can I overide the pin choices to what I need?? Can you add a preferences file it must consider?

KP_0 = (q1);

P22V10G Programmed Logic:
-----------------------------------------
KP_9.D   = (  KP_8.Q ); " ISTYPE 'BUFFER'
KP_9.C   = (  CLK_ );
KP_9.OE  = (  EN );

KP_8.D   = (  KP_7.Q ); " ISTYPE 'BUFFER'
KP_8.C   = (  CLK_ );
KP_8.OE  = (  EN );

KP_7.D   = (  KP_6.Q ); " ISTYPE 'BUFFER'
KP_7.C   = (  CLK_ );
KP_7.OE  = (  EN );

KP_6.D   = (  KP_5.Q ); " ISTYPE 'BUFFER'
KP_6.C   = (  CLK_ );
KP_6.OE  = (  EN );

KP_5.D   = (  KP_4.Q ); " ISTYPE 'BUFFER'
KP_5.C   = (  CLK_ );
KP_5.OE  = (  EN );
...etc...

I prefer not to have to hand edit outputs every time I generate a change. Suggestions? I have OPALjr. if that helps.

I tried shuffling I10, I9, I8, I7... etc into the order I wanted and no change. I tried moving "Q inputs" to the output blocks to try to match what it was doing to what I wanted, and no change, it just undid what I shuffled.

---- Have I solved this?? ----

\ispTOOLS5_1STRT\Projects\registerproject.TT3

I edited .TT3 in a text editor so the pins are diplaying where I want.

#$ PINS 13 Din:2 CLK_:1 EN:3 KP_9:14 KP_1:22 KP_2:21 KP_3:20 KP_4:19 KP_5:18 KP_6:17 KP_7:16 KP_8:15 KP_0:23

when I re-run the compile, it draws me a chip as I wanted. Running "Create Fuse Report", then "Chip Report", it shows me what I want to see.

I have not burned a chip to try it yet. I am wondering if it modified the JED properly?

Ok, I hand-edited the JED file, and I believe I got it correct.

I don't know how to check if the checksum was altered, but since I replaced every zero I moved, hopefully the checksum is intact.

Previously asked & solved:

Pin Assignment in ispLEVER Classic

Typical file location as example:

C:\ispTOOLS5_1_....\examples\spld\gal\mlcount editing the mlcount.tt3 file then :

"After done, just run the 'Fit design' (+create fuse map) again and voila, you have the right signals at the right place."

Slightly more detail:

Open "examples" in isplever, choose and open mlcount.syn

"create fuse map".

New file appears mlcount.tt3 (make a backup)

Open mlcount.tt3 in txt editor.

"#$ PINS ....." is the line you are looking to modify in your code.

Save your edited file and re-run "create fuse map". (be sure your edited file saved is ".tt3" and not ".tt3.txt"
