I've cpf and rtl available with me. Now need to insert Lowpower cells in the netlist.
Please tell which compiler should i use to generate netlist which understands power-intent
written in CPF and accordingly place the lowpower cells in the netlist.
Thanks in advance.
I am using Cadence RC but it is not reading CPF and asking for another License
"RTL_Compiler_Ultra_II_Option". Does another license is needed here or it is setup issue.
In reply to NTlp:
it looks your version of RC is not up to date. Depending on the version of RC you are using, CPF usage will need you to have GXL license add-on or the Advanced Low Power add-on. Please check with your AE or sales person on this
In reply to grasshopper:
Yes, i don't have GXL license.
I have RC72 and Conformal92(Conformal_Lowpower) license so thought to work on
a dummy design, providing the CPF and checking the results on the netlist.
But it seems for working with lowpower design(i.e. reading cpf files) need separate license).
Tell me if i get netlist with lowpower cells being inserted that i can do manually than running GLS for lowpower
design needs separate license or it is ok.
RC72 is 6 years old and LEC92 is 4 years old. Both versions are no longer supported so I would certainly encourage you to move to more up to date releases. It is not just a question of support but also there have been numerous issues addressed since and the CPF version supported back then was 1.0 and now it is either 1.1 or 2.0. Furthermore, I am not even sure CPF was a standard in the RC72 time frame.
CPF work indeed requires you to have the GXL or Advanced Low Power license. As per inserting the LP cells manually and running standard synthesis, this is certainly possible but it will not lead to best QoS and you certainly risk implementation bugs introduced by your LP insertion solution. Some of those issues can lead to dead silicon as you probably know. For example, inserting incorrect isolation logic on the power domain controller just to mention one.
hope this helps,
Yes, i understand. It should be RC111 and Condormal12.1
I would even recommend using RC121 if that is a possiblity. 121 has been out for some time already
