V2.1i COREGEN, C_IP2: Known Issues in the C_IP2 IP Update

Description

Keywords: coregen, c_IP2, ip, known, multiplier, sine, cosine, virtex

Urgency: hot

General Description:
C_IP2 IP Update Known Issues

Solution

VHDL Simulation Analyze Order:
(Xilinx Solution #6250) has been updated to indicate the order in which
the VHDL behavioral simulation models must be analyzed for this
release.

Known Issues

1. (Xilinx Solution #7409) V2.1i COREGEN, FOUNDATION: Optional pins
which are not requested still appear on the Foundation symbol for a
CORE Generator Core

2. (Xilinx Solution #6853) - V2.1i COREGEN, F2.1i FOUNDATION, NGDBUILD:
Unexpanded block error -- ... because one or more pins on the block ... were
not found

3. (Xilinx Solution #7391) - C_IP2, V2.1i COREGEN: Virtex Variable
Parallel Multiplier "Set Overrides Clear" option behaves the same way as
"Clear Overrides Set"

4. ((Xilinx Solution #7393) - C_IP2, V2.1i COREGEN: Virtex Variable Parallel
Multiplier module latency does not match the 4K (XC4000) version of the core

5. (Xilinx Solution #7396) - C_IP2, V2.1i COREGEN: Virtex Variable Parallel
Multiplier "Combinatorial" and "Pipelined Registers" option interaction

6. (Xilinx Solution #7441) - V2.1i COREGEN, C_IP2: "ERROR: Unable to find
library for core Sine-Cosine_Look-Up_Table|xilinx|xc4000_all"

Also, the known issues documented for the C_IP1 release still apply, as
documented in (Xilinx Solution #7149).
