4.2i Foundation - Functional Simulation: Initialization attributes and files for RAM components do not work in functional simulation

Description

Keywords: block RAM, initialization, functional simulation INIT_0x, RAMB4_Sx, FIR Filter

Urgency: Standard

General Description:
Foundation Functional Simulation initializes RAM components to zero even if the initialization has been applied using attributes or initialization files in CORE Generator.

(Because the CORE Generator FIR Filter uses RAM to store the coefficients, this answer applies to this filter as well.)

Solution

There are two resolutions to this issue:

1. Perform Check Point Simulation using the .ngd file.

2. Perform timing simulation only.
