4.2i Foundation - Functional Simulation: Initialization attributes and files for RAM components do not work in functional simulation
Keywords: block RAM, initialization, functional simulation INIT_0x, RAMB4_Sx, FIR Filter
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.)
There are two resolutions to this issue:
1. Perform Check Point Simulation using the .ngd file.
2. Perform timing simulation only.
