Problem Title:
F1.5i: Functional/Gate level Simulation on flatten EDN give 'Warning 9199: Unknown component
- U1, sym_name.
Problem Description:
Keyword: EDN, EDIF, create, macro, from, netlist
Urgency: Standard
General Description:
Functional gate level simulation can be generally done by clicking
the simulation button from schematic editor. However, when done
on a project with symbol created from netlist; this result in several
similar warnings:
Loading - M1616SR5
Forcing zero-delay default timing values
Warning 9199: Unknown component - U1, VREG16E1
Warning 9199: Unknown component - U10, M16X2SR1
Warning 9199: Unknown component - U11, DEL2X3_0
Warning 9199: Unknown component - U12, ADD18SR0
Warning 9199: Unknown component - U13, REG2RE0
All the components and its functionality are instantiated in the flatten netlist (.EDN file).
However, simulating this design result in unknown (Z) value.
Solution 1:
Foundation gate simulator is not translating the lower level simulation
modules appropriately. There are two workaround for this:
1. To simulate the particular netlist(edn file) by itself:
Go to Project Manager window-> Tools->Simulation/Verification->
Gate Simulator.
On the popup window, select 'netlist to load', click OK, then select
the netlist -> open, and you are ready to simulate.
2. To simulate your whole project with the netlist in it:
Click on the implementation button on Project Manager (PM)
Window -> Run the design and stop after translate (the first step).
In PM window, click on Tools->Simulation/Verification-> Checkpoint
Gate simulation Control...->select an NGD file and click OK->you are
ready to simulate.
