As you said you are looking for XS Classic options and XS Advanced options (which is the preferred way cause XS classic is set to deprected) the answer is yes for both. But you have to consider that both free trial options on the SAP Cloud Platform are not for productive usage.

XS Classic: You have to setup a HANA MDC instance (check tutorial Setup your trial SAP HANA MDC instance). You can access the instance using the HANA web-based development workbench (a link is provided in the database/schemas area for your MDC instance, after you have created it), which you can use to create a calculation view. You are also able to connect with SAP HANA Studio or Eclipse with installed HANA tools.

XS Advanced: On SCP the XS Advanced Model is available via Cloud Foundry. Therefore you need a SCP Cloud Foundry trial account (check tutorial Getting started with Cloud Foundry). You can connect to the Cloud Foundry trial account via the SAP Web IDE Multi-Cloud Version. You can create a Multi-Target Application project which can be deployed to the XS Advanced Runtime. One issue at time of writing this is, that the SAP Web IDE Multi-Cloud Version does not support all HANA artifacts at the moment. So you are not able to create directly calculation views. One workaround would be to use HANA Express to create your XS Advanced Application (including the calc. views) and deploy it to SCP Cloud Foundry (details on that can be in blog post Develop in SAP HANA Express and Deploy to the SAP Cloud Platform Cloud Foundry).
