AR# 5209

V1.5, V1.4 CORE Generator Data sheet, 4K RAM - CLB utilization formula is incorrect for odd-valued single-port 4K RAM sizes (sizes of the form 2N+1)

Description

Keywords: RAM, data sheet, datasheet, CLB, utilization, data

Urgency: Standard

General Description:
Table 2 in the Synchronous (single-port) RAM data sheet
incorrectly indicates that for data widths of the form, 2N + 1
(odd-numbered data widths), the CLB utilization is N.

This is incorrect.

Solution

The correct value is N+1; it is solely dependent on the fact
that there are only two flip-flops per CLB in the 4K
architecture.
