Quartus 2 synthesis problem

[fguihot]

Hi everybodies !!!
I 'm programming CPLD on Quartus2 5.1 sp1 web edition.
I'm an user of Max2plus, and I migrated to quartus2.
I am unable to obtain the same results.
I'm used to programm in AHDL, but quartus 2 does code simplification, and doesn't provide any means to empeach these simplification in AHDL.
I'm migrating to VHDL/Verilog, which provide more control other code (als it is more high level language), but still, quartus 2 does code simplification, even with options such as "preserve register", "synthesis keep".
So I have a terrible feeling. Does it is a FPGA oriented software, sold for CPLD, but without any CPLD functionnalites ???

i think you can use quartus to design the cpld,i usually use isplever
