Hi,
I try to change the LUT output value by the command " modify_lutmask "
The TCL file includes the content : modify_lutmask -to eco_sig_1_cZ~0 -mask 0x1
But I get errors when I begin the perform ECO compliaction :
Error (19796): Atom 'eco_sig_1_cZ~0' (atom id: 2949): Oterm DB_OPORT_COMB_OUT : 0 depends on unconnected iterm type DATAB File: /tmp/ymiller/Premier/gale_bonsai_bt_only_fpga_23ww02_09_112832/rev_MX_2/par_1/premier_fpga_top.vqm Line: 294036

what is my wrong ? should I change the ECO command ?

Hi Yishay,
As mentioned above, you need to connect the DATAF port.
Add connection to DATAF port https://www.intel.com/content/www/us/en/docs/programmable/683873/current/change-routing-connections.html

Hi Nurina,
If I sum up what you're saying ,
1) when I want to mask spesific LUT - I must mask all others LUT even I dont want to do it .
2) I should be aware that "mask" ECO most of the time doesn't enough , I should do more ECO commands like "make connection"
Agree ?

Hi Nurina
I would like to suggest an improvement to the ECO capability. Please consider enabling an option to mask specific LUTs, as this would provide several advantages:
-
Mask all LUTs somtimes generate more ECO commands (like make connections) as we see in the previous examples .
-
When the ALM component is used for two or three glue logics that are not related to each other, masking all LUTs can be more difficult.
