Subject: Why Are There Odd Question Marks In My Synthesis Log Files ???
Hi John,
Could somebody help me to understand why I get sometime the question marks
for a certain register in my synthesis log file. A part of the log file
looks like this:
======================================================================
Register Name | Type | Width | Bus | MB | AR | AS | SR | SS | ST
======================================================================
cnt_reg | Flip-flop | 8 | Y | N | N | N | N | N | N
dac_buf_reg | Flip-flop | 1 | - | - | N | N | N | N | N
data_buf_reg | Flip-flop | 8 | Y | N | N | N | N | N | N
mod2cnt_reg | Flip-flop | 1 | - | - | N | N | N | N | N
sum_reg | Flip-flop | 8 | N | N | ? | ? | ? | ? | ?
======================================================================
The register bank sum_reg got the question mark for all parameters:
AR, AS, SR, SS, ST
Thanks for any help.
