1. Original design:
|
|
|
|
Function Mcells FB Inps Pterms IO
|
|
Block Used/Tot Used/Tot Used/Tot Used/Tot
|
|
FB1 18/18* 27/54 69/90 6/ 9
|
|
FB2 18/18* 34/54 60/90 8/ 9
|
|
FB3 18/18* 19/54 32/90 5/ 9

72/72 117/216 217/360 26/34
|
|
|
|
|
|
2. New design, with RGB mux, switch pass throughs, etc commented out
|
|
(failed to map sp_reg<9>, hence one less macrocell)
|
|
|
|
Function Mcells FB Inps Pterms IO

3. Change from csync=>S to csync=>CSYNC1 (as passthroughs still use up a macro cell).
|
|
(now fits)

10. Reverted to original .xise file
|
|
Cleaned up design to remove SW2/3 pass throughs
|
|
Used gpio22/23 for mode7 / sp_data
|
|
Used gpio19/26 for sw2/3 (not via cpld)
|
|
(same result as 4 above)

11. Final design on 5/6/2018
|
|
|
|
(Added SW2, SW3, Link as unused inputs)
|
