XCELIUM20.09 不支持spectre_fx

lovepuyu

数模混仿时，想用xrun + scpectre_fx
结果报错：
    amsspice: Error: unrecognised option(s) scpectre_fx

不知道是版本问题还是设置问题，请大佬支招

你的spectre是什么版本？FX需要211.
X的话201就可以

Since you are currently interested in FX, just add these lines to your lic file:
FEATURE **spectre_FX_sc **cdslmd 21.1 permanent uncounted HOSTID=ANY SIGN2
FEATURE **Spectre_FX_sc_kernel **cdslmd 21.1 permanent uncounted HOSTID=ANY SIGN2
FEATURE **Spectre_FX_cpu_accelerator **cdslmd 21.1 permanent uncounted HOSTID=ANY SIGN2
(1) When you added "Spectre_X_MMSIM_Lk" in your lic file you are "met the prerequisites" for run Spectre X solver, because you already have base MMSIM-token feature that named "Virtuoso_Multi_mode_Simulation".
All "_MMSIM_Lk" features this is a special "lock" license. (All "_Lk" means "lock", not only MMSIM).
When you are using Spectre X via MMSIM-token (e.g. if your lic file didn't contain "PRODUCT" features), Spectre checked out base feature Virtuoso_Multi_mode_Simulation and an equivalent quantity of "lock" licenses (in that case - Spectre_X_MMSIM_Lk). You cannot use only "lock" license, they checked out in conjuction with base MMSIM-token.
(2) Since you have figured out this problem, I will not comment on it.
Just as useful information:
This is not exactly the right way to use MMSIM-tokens. Yes, unlimited licenses are good.
But if you imagine a situation where they are limited, its real headache. If you run a large number of simulations via MMSIM-token using the Spectre, APS, XPS, X, they all eat up your base MMSIM-tokens, then you can get a problem when for new simulations you simply do not have free licenses. That is why, when starting the simulation, Spectre checks the availability of licenses for "PRODUCT" first, and then for "MMSIM-tokens".
For Spectre X the normal "PRODUCT" features is "**spectre_X_sc **+ Spectre_X_cpu_accelerator" in which (the first give to you a single-core base license and the second give to you multi-core/multithread license /1 lic for 4 core, 2-16, 3-64, 4-128.. up to 512 core/).
About FX features, for now they didn't provide "Spectre_FX_MMSIM_Lk" because this product very fresh. I expect this feature to appear in product 90007, due out in Q3 2022, along with the 22.10 major release.
(3) To use FX in AMS, you need to follow these steps:
a) First of all check if you have this feature in your lic file:
Virtuoso_MMSIM_Incubation
Add this feature if you haven't it.
b) After you create config, click button ADE Explorer in Hierarchy Editor. In ADE Explorer goto "Setup/High Performance Simulation", choose "Spectre" and "Do not override".
c) Then goto "Simulation/Options/AMS Simulator" click on button Additional Arguments, then in new window check "Enable", and type in "Additional Arguments" field:
-spectre_args "+fx"
d) Then goto "Simulation/Netlist and Run Options" and check "Enable AMSD flexible release matrix", then check "Change Spectre path" and select the full path that ends on SPECTRE211/bin, for example in my way /home/$USER/cds/SPECTRE211/bin
Save all if that needed, in the main window of ADE Explorer, do not forget to specify all parameters that you needed and start simulation.

我单独使用spectre fx 是可以的，就是混仿时不行

经过检查，这些FEATURE存在于license中。
还是感谢您

我的版本跟你差不多，我是按照上面(1)(2)....设置跑的混仿，可以跑起来，但是速度不及VCS+XA

cotonier

你用ade explore或者ade assembler设置一下high perfomance那里的FX选项，如果有的话。
adel的话比较麻烦，检查一下你是不是设置对了，ams option那里选项加的spectre_args格式对不对。(-spectre_args "xxxx")
另外都要设置使用外部spectre来仿真，在'netlist and run options'勾选‘enable AMSD flexible release matrix'

yylei

你确定拼写正确了？scpectre_fx?
