V1.5, V1.4 COREGEN DATASHEET, 4K RAM: CLB utilization formula is incorrect for odd-valued Single Port 4K RAM sizes (sizes of the form 2N+1)
Record #5209
Product Family: Software
Product Line: Coregen
Product Part: Coregen datasheets
Problem Title:
V1.5, V1.4 COREGEN DATASHEET, 4K RAM: CLB utilization formula is incorrect for odd-valued
Single Port 4K RAM sizes (sizes of the form 2N+1)
Problem Description:
Urgency: standard
General Description:
Table 2 in the Synchronous (Single Port) RAM datasheet
incorrectly indicates that for datawidths of the form, 2N + 1
(odd number data widths), the CLB utilization is N.
This is incorrect.
Solution 1:
The correct value is N+1 and is solely dependent on the fact
that there are only two flipflops per CLB in the 4K
architecture.
