9.2i EDK - # ** Error: system_init.vhd(12): Component instance "ramb16bwe_0 : ramb16bwe" not found. - Spartan-3A structural / timing simulation

Description

When I try to do an EDK structural simulation for a Spartan-3A part, I get the following error messages: 

 

 # ** Error: system_init.vhd(12): Component instance "ramb16bwe_0 : ramb16bwe" not found. 

 # ** Error: system_init.vhd(83): Component instance "ramb16bwe_1 : ramb16bwe" not found. 

 # ** Error: system_init.vhd(154): Component instance "ramb16bwe_2 : ramb16bwe" not found. 

 # ** Error: system_init.vhd(225): Component instance "ramb16bwe_3 : ramb16bwe" not found. 

 

For a timing simulation, I get the following errors: 

 

 # ** Error: system_init.vhd(12): Component instance "ramb16bwe_0 : x_ramb16bwe" not found. 

 # ** Error: system_init.vhd(83): Component instance "ramb16bwe_1 : x_ramb16bwe" not found. 

 # ** Error: system_init.vhd(154): Component instance "ramb16bwe_2 : x_ramb16bwe" not found. 

 # ** Error: system_init.vhd(225): Component instance "ramb16bwe_3 : x_ramb16bwe" not found.

Solution

Structural Simulation 

The work around for this structural simulation problem is to open the system_init.vhd file and change: 

 

for ramb16bwe_0 : ramb16bwe 

use entity unisim.ramb16bwe(ramb16bwe_v) 

 

to: 

 

for ramb16bwe_0 : ramb16bwer 

use entity unisim.ramb16bwer(ramb16bwer_v) 

 

Timing Simulation 

The work around for this timing simulation problem is to open the system_init.vhd file and change: 

 

for ramb16bwe_0 : x_ramb16bwe 

use entity simprim.x_ramb16bwe(ramb16bwe_v) 

 

to: 

 

for ramb16bwe_0 : ramb16bwer 

use entity simprim.x_ramb16bwer(ramb16bwer_v)
