Quatus II; Wo kann man die Option "Add Pass-Through Logic to Inferred RAMs" finden?

[Tomy (Gast)]

Hallo zusammen,

ich versuche gerade den IP-Core EtherCat Vom BeckHoff in Quartus II 
Version 12.0 einzubinden. Es wird empfohlen dass man die Option "Add 
Pass-Through Logic to Inferred RAMs" unter "Settings/Analysis & Settings 
/ More Settings... " ausnehmen sollt.

Ich kann aber die Option nicht finden....:(

Kann jemand mir helfen?

Vielen Dank im Voraus!

Lg Tomy

Auto RAM Replacement vielleicht?


Allows the Compiler to find a set of registers and logic that can be 
replaced with the altsyncram or the lpm_ram_dp megafunction. Turning on 
this option may change the functionality of the design.

hallo,

ich glaube nicht...

Laut Quartus II Help Doc:
"A logic option that allows the Compiler to add extra logic to inferred 
RAM blocks requiring a read-after-write mode that is not supported by 
RAM blocks in the current device. When a design reads and writes to the 
same memory address, this extra hardware guarantees that the read 
returns the new data being written to the address. However, the extra 
logic increases the area of the design and possibly reduces its 
performance if the design's critical path includes the inferred RAM.
This option must be applied to an inferred RAM block or it is ignored. 
This option is available for all Altera devices."
