AR# 10815

WebPACK - XPLA3 Latch fails in timing simulation.


Urgency: Hot 


General Description: 

A simple latch functionally simulates properly, but fails in timing simulation.


This is fixed in the latest version of the WebPACK XPLA Fitter Module, which is 

available for download at:

The work-around for older versions of software is to open the time_sim.vhd file and look  

for the process statement that contains the latch; add the data input into the sensitivity list. 




process(LH, AP, AR, D


if AR = '1' then 

Q_local <= '0' after tar2q; 

elsif LH = '1' then 

Q_local <= D after tLDI; 

elsif AP = '1' then 

Q_local <= '1' after tap2q; 

end if; 

end process;
